How many HP does K&N air filter add?
However, K&N intakes typically add an average of 15-25 additional horsepower over a stock system**. Each kit undergoes significant testing to help ensure that the filter and intake tube are positioned to deliver large increases in airflow and horsepower.
Do K&N Intakes Increase Power? K&N intakes typically add an average of 15-25 additional horsepower over a stock system. Because vehicle makes, models, and engine sizes vary widely, along with vehicle condition, power gains also vary across applications and individual vehicles.
In short, yes, performance air filters offer an increase in horsepower. On average, this increase is around 3-5 HP. Despite being a minor increase, the added horsepower can go a long way in terms of improving the overall performance of your vehicle, along with enhancing the overall driving experience.
K&N filters offer exceptional airflow to your engine - and more airflow often translates to more efficient fuel burn. Disposable filters aren't typically designed with the performance enthusiast in mind; they are designed to be simple, cheap, and functional.
Disadvantages of Buying K&N
Because K&N filters use an oiled filtering element, there may be long term problems in vehicles equipped with mass air flow sensors, as oil can build up over time and cause fouling or errors in the sensor which require cleaning.
According to the research conducted by our review team, the cold air intake that adds the most power is the Spectre Performance Air Intake Kit. This is due to the fact that this cold air intake offers up to 50 percent more airflow than factory box air filters and intake tubes.
Depending on the way the driver handles the vehicle and the way the motor is tuned, these filters may increase horsepower very minimally (~5hp or so) and may also increase fuel mileage slightly as well.
Simply replacing your engine air filter can increase horsepower and, in some cases, even improve mileage. So, we would advise changing your engine filter at least once a year or what is recommended in your vehicle owner's manual. It is always best to follow the recommendations of the vehicle manufacturer.
The latest “improved” manifolds can often generate an additional 20, 30 or even 50 or more horsepower on many of these larger displacement engines compared to what was possible using an older manifold design. Runner length also affects the rpm range where an engine makes the most power.
If your filter doesn't fit properly, it can interfere with the flow of air from the system to your home. Your air filter may also get sucked into the system, causing damage. Improper installation of the filter or the absence of a filter allows dust and other debris to build up inside the system.
Do K&N air filters let more dirt in?
As a result, K&N filters are able to hold significantly more dirt and particulate matter per square inch of media over an average paper filter.
A stock paper based filter loads its surface with dust in due course of driving while in the case of a K&N filter, there are multiple layers of fibres holding dust particles. Thus a K&N filter claims to effectively hold more dirt per square inch than a paper filter.

K&N High-Flow Air Filters™ are designed to last for the life of your vehicle, and are protected by a Million-Mile Limited Warranty. With normal use, they can go up to 50,000 miles before a cleaning is needed (the larger conical filters included with K&N intake systems can go up to 100,000 miles between services).
With a K&N air intake system, you're not just promised an increase in horsepower and torque—it's guaranteed. K&N air intake systems are designed to direct airflow more efficiently than factory intake systems, increasing the efficiency of your engine's combustion process.
Besides increasing horsepower and torque, a K&N cold air intake system will save you time and money. Every K&N air filter can be washed and reused over and over again. So, you won't have to buy a new air filter every 10,000-15,000 thousand miles.
The more oxygen (air) that flows into the engine, the more fuel that can be burned, and the more power the engine can make. To say it another way, assuming you mix the correct amount of fuel with the air, how much power an engine can make is dependent on airflow.
Depending on your car, an aftermarket performance exhaust system could give you as much as 50 extra horsepower or as little as 2-3 HP. To learn more about the benefits of upgrading your exhaust system or get an estimate of the horsepower benefits one might give you, try asking an expert.
Fenske also tests out the filters in a real-world environment, testing acceleration times between the four candidates. Like on the dyno, he sees incremental increases, with the K&N filter coming out on top. It produced a 2-3 percent improvement in acceleration time versus the stock unit.
When you have a fresh air filter, a free flow of clean air is getting into your engine, which means it requires less actual gas to go as far. In other words, more air means better gas mileage, so change that air filter as soon as you need to. The air filter is a big part of efficiency.
Can air filter improve mpg?
The benefits of a new air filter are immediate – a replacement can increase your MPG by up to 10%, saving your fuel costs. The more debris your filter prevents from entering your engine, the further your vehicle's lifespan is likely to be extended.
Use the stock Dry air filter, it is designed to flow more air than your car would ever need. A k & n uses oil which has a reputation of coating mass air flow sensors (a bad thing). The only way it can flow more air is to filter less!
And if your engine is getting more air, then it can perform better. In fact, a high flow air filter can actually increase your horsepower by about 3 to 5 HP and increase your torque as well. At the same time, this can lead to increased fuel efficiency.
The latest “improved” manifolds can often generate an additional 20, 30 or even 50 or more horsepower on many of these larger displacement engines compared to what was possible using an older manifold design. Runner length also affects the rpm range where an engine makes the most power.

Do carb spacers add horsepower?
If you're building an engine that is destined for the street, a carburetor spacer may not give you a lot of horsepower in a usable range. They will add a little bit of power way up top, but only if you need the extra plenum height to match up with your camshaft and cylinder head combination.
Cold Air Intakes are said to improve your vehicle's performance by 5-20 horsepower. This number will vary depending on the make and model of your vehicle. While this isn't enough power to put you back in your seat, it will give your car or truck a little pep in its step.
The cold air intake does typically get denser air than the stock intake. However, since it is longer and more requires more complex routing, it is often more expensive. This increased complexity also leads to a more difficult and time-consuming installation.
In those tests, the K&N filter did indeed provide greater airflow and less resistance. However, that added volume came at a price. While more air is good for performance, it turns out that the more free-flowing filter also allowed more dust and dirt particles to pass through the intake.
