Does K&N Air Filter Damage The Engine?

No! K&N air filter offers a better filtration and airflow as it has cotton gauze/oil cleaning and re-oiling at the appropriate intervals, long lasting,re-usable and boost engine performance at minimal cost.

But this does not mean that the product is without shortcomings: every product has its share of shortcomings. And like such products, the K&R air filter has its issues.

So, if you choose to install K&N, you will have to do with such cons.

Fortunately, you will be enjoying many pros when using K&N that the cons might seem insignificant in the light of what you stand to gain.

For instance, installing K&N offers you lasting power. Unlike your regular filter, K&N air filters happen to be long-lasting, making them a better investment for your vehicle.

And you might be amazed to know that they can last and age with your car. Again, the K&N air filter increases the performance of your car, even as it puts more mpg.

And because it’s re-usable, there will be no need to buy other filters as you only need to clean and re-oil, bringing your engine back to a good condition.

This means that you will save money you could have used to buy a new filter every other time.

Lastly, you will enjoy a better fuel economy with a K&M air filter due to the improved airflow.

Do Performance Air Filters Damage Engines?

No, If you use performance air filters, you want an improved performance but not any damage to your engine. Performance car air filters have a pretty simple functionality.

Their function is realistic as it generally revolves around filtering the dirt and dust particles from the air sucked into the engine before reaching any engine component or sensor.

If these particles are let to get to such components and sensors, they will occasion damages.

Luckily, performance air filters sit at the start of the induction piping before the important sensors like air flow meters.

Coming in numerous shapes, materials, and sizes, performance air filters have a varying cost and flow capability.

Such variables, combined with their placement location, determine the effectiveness of performance air filters in a performance application.

But as expected of all filters, performance filters will only process a certain amount of air based on their size, meaning that smaller filters will restrict the power potential of your engine significantly.

So you might want to test this by fitting a vacuum gauge after the filter to ascertain if there is any vacuum.

A smaller filter will occasion a vacuum, but it’s best to fit the biggest air performance filter and it might be too complex for a layperson.

Are K&N Filters Better Than Stock?

Yes,K&N filtersare better than stock. As you might be aware, the filtering element in stock filters is from a special paper grade. This grade paper traps dirt and other particles.

Stock filters are very cheap and are easy to replace. This filter will work well as long as you replace them on time.

However, I need to point out that stock filters do not allow sufficient airflow, thus hindering the engine from working at its full capacity.

Unlike what many people believe, a car seriously needs gasoline to run and a sufficient air supply.

And because stock filters want in this area, K&N filters might be what your car needs.

Any motorist would be happy if there was a single way to magically transform their cars into better-performing cars by simply swapping out a part and reap the benefits instantly.

This is probably the mentality that has led to the rapid universal acceptance of K&N filters.

As I alluded to, the airflow rate affects the performance of your vehicle’s engine; K&N filters come in handy since they forego the paper set up, creating a more porous entrance for air.

This is done using an oil-based material that happens to be more porous.

How Much HP Gain With K&N Filter?

When you install a K&N filter, you will be expected to register a gain of about 10-15 horsepower increase.

Additionally, K&N filters come with a 10-year/Million Mile Limited Warranty, guaranteed to increase your vehicle’s horsepower.

What’s more, you can check them out for all the different intakes they have to offer.

Does The K&N Air Filter Make The Car Louder?

It depends on how you view it. If you compare a brand new K&N filter with an OEM air filter, the answer will be No.

If you had a clogged-up OEM filter, it’s indisputable that you will notice that the car will get faster. But that is not the case as you will just have restored the car to the factory HP.

But I agree that some K&N filters’ intakes will make the car potentially loud if things like the OEM resonator are eliminated.

An OEM resonator is merged into the air intake track using their intake pipe and a filter.

The resonator eliminates the sounds of the motor occurring with the throttle wide open. This is very pronounced.

But I want to point out that your car will never run faster than the Manufacturer’s stated HP. Indeed, it will mostly have less HP due to mechanical loss to the wheels and wear.

But you can have an exception if the ECU is replaced or overwritten with a tune or tunner device to modify the original ECU.

However, an air filter will provide minute gains that are not noticeable.

Using K&N filters in my cars, I have noticed measurable improvements in fuel mileage and performance over the years.

Does K&N Drop-In Filter Change Sound?

No, In most instances, you won’t be able to notice a thing. But if you are overly keen on sounds and noises, the difference it’s not that much.

However, if you are driving a forced induction car, you can’t help but notice a nice gain of blower whine.

But what I would like you to realize is that even with the turbo spool with a drop in K&N, it will still want to be compared to a full-blown exposed cone filter, like you expect from a CAI will be much more than the stock filter.

On the other hand, if installed on a V8 with exhaust and headers, a K&N air filter will guarantee the engine’s different “tone.”

But this is not necessarily louder; you only get a different pitch. It will take a trained ear to notice any loudness in such cases as the loudness is minimal.

While you might consider the $55 a year overly priced, you forget to factor in the cheaper option of installing the $16 filters.

These will have to be installed four times in a single year, making them more expensive K&N is the got to option.

Yes, installing the conventional filter will be more expensive in the long run and more time-consuming s you have to change than even about three months or so.

How Much Horsepower Does Cold Air Intake Add?

A cold air intake, a frequent performance upgrade primarily due to horsepower gained, increases between 5 to 15 horsepower.

However, depending on your model, make, and engine size, this can be lower or higher.

Being relatively easy to install, cold air intakes give truck owners the perfect project for getting to know their engine, complete with a noticeable power upgrade.

The 5 to 15 horsepower I have mentioned above is attributable to several factors. These include the location of the upgraded air intake.

Cold air intakes come in handy in typically moving the system from its stock location to make it breathe in some denser, colder air near the fender well instead of the lighter, hotter air over the engine.

Consequently, there is a promotion of better combustion. And ram-air intakes use a large air duct at the front-most part of your vehicle’s engine bay.

This sends air into the system before it gets heated by the engine. Due to the wider intake, more air is allowed into the system, supporting unrestricted airflow.

Generally, air filters in upgraded air intake systems are larger than stock. And this supports increased flow.

Filtration is better, thanks to the materials used since cotton are better than paper. Still, the materials are oiled as opposed to dry in the conventional one.

Is A Bigger Air Filter Better For The Car?

Yes, a bigger air filter will serve you better than a small one. For those tired of the frequent changing of air filters, I advise you to invest in a high-flow air filter.

Unfortunately, this scarcely comes as part of the routine maintenance that we carry out on our cars.

But this is something you need to be conscious of since, regardless of how small it might seem, the air filter can make a significant impact on your car.

It’s recommended to change them yearly, regardless of whether they are dirty-looking or not. If your car’s air filter is clogged, your vehicle will suffocate.

Consequently, you will notice decreased power because of a dirty air filter. When it gets to that, all you need to do to solve the problem is buy a new filter and install it.

Many people believe that you will need to do this once a year. But this is not always the case. Your car can do better if you install a high-performance filter.

Unlike regular filters, a high-flow filter doesn’t need to be changed every year. Indeed, you might only need to clean it after every other year or so.

Their characteristic of not getting clogged makes this a reality, even as they offer better airflow to your engine.

Does The Size Of The Cone Air Filter Matter?

Yes. It’s given for the size of the air filter to affect the airflow. But either way, you will need to keep the same diameter intake tube.

Since air filters have different densities, some are more restrictive than others. If you restrict your car’s airflow, you can be sure to get problems.

It is, therefore, safe to go bigger but not smaller. While a bigger CAI won’t add HP, the sound will change slightly due to the lesser restriction.

But if all you want is a better sound, you can be sure to get that cool “whoosh” in addition to a slightly deeper sound that you will get from the bigger cone.

You will want to check the dimension of the cone filter provided for CAI systems. As alluded to already, you can go bigger with no trace of problems but don’t go smaller.

Fortunately, the K&N comes with either 3 or 4 inches of the adapter. Therefore, it is easy to find what you want and fit your specific situation.  

When I was installing mine, I took well over 30 minutes because of the mods I had to do.

Does A Cone Filter Increase Performance?

No, A cone filter will not increase performance even though it is designed to install performance vehicles.

Since cone filters are used in performance cars, that alone occasions manifold confusion.

While its sound might be exhilarating to some, this filter, a part of an induction kit equipped with the pipework, is meant to suck in cold air mostly.

Consequently, it’s to be found close to the airflow in the front of the car.

Unfortunately, many people install such devices on their cars without knowing they won’t make any difference in their driving performance.

Additionally, if we are talking of a regular car, you will also be required to replace the stock airbox.

All you need to know is that the noble idea behind a cone filter is getting more air into your engine. The presence of more oxygen in the engine will dictate more power for the car.

Such benefits are only enjoyable for performance engines but not regular engines.

Therefore, installing a cone filter might only bring a different sound to your car and not much more.

Not all cars benefit from cone filters, so it will be misleading to claim, as some ignorantly do, that cone filters improve performance.

This is just one of those devices that will not accommodate a blanket statement in terms of functionality.


K&N filters do not damage the engine.
