K&N E-2429 Replacement Air Filter

Product Details

Product Description

The Original High-Flow Air Filter. Since 1969 K&N Engineering has been designing, manufacturing, and enhancing High-Flow Air Filters for the automotive and motorcycle enthusiast interested in maximizing horsepower and acceleration. Since our humble beginnings we have designed and manufactured over 2,400 High-Flow Air Filters to fit most modern passenger vehicles and over 500 High-Flow Air Intake Systems to fit vehicles driven by enthusiast minded drivers. We not only have more applications than any other manufacturer of similar product, we invented the High-Flow category and the High-Flow Technology that supports it. K&N also makes thousands of racing and specialty type air filters and is the only air filter used at the Indianapolis 500 Race®. The K&N FilterCharger® air filter is designed to achieve high, virtually unrestricted air flow while maintaining filtration levels critical to ensure long engine life. Our automotive OE (original equipment) replacement air filters generally add 1-4 horsepower. The secret to our success lies in the unique characteristics of our filter medium that was originally developed by K&N all those years ago in the dust, sweat and tears of desert motocross racing. We just wanted to win races and stumbled on a cotton filtration technology destined to be great. Our high flow cotton gauze air filter is washable, reusable and built to last for the life of an automotive or motorcycle engine. K&N air filters consist of four to six sheets of cotton gauze layered between two sheets of aluminum wire mesh. This media is then pleated and oiled to enhance its filtering capabilities and overall performance. K&N Air Filters were created for an environment requiring maximum horsepower and enhanced acceleration in addition to protection from the dirt and dust of off-road racing. The result is an air filter that allows dramatically more air into an engine, is washable and reusable, and will protect your vehicle.

Customer Reviews

Its ok, somewhat disappointed
Its ok, I just expected more from this.
I noticed my MPG went down about 1 mpg vs the stock model that came with the new car.
But That could mean that this one is better at filtering more than the stock model. I'm no expert in cars but that could be a possibility. I do know that there is usually a trade-off between filtering and airflow. If I had to do over, I would have gone with the less expensive stock model that kept the MPG were it was as I don't plan on keeping the car well into its prime where the benefits of better filtering would extend the engine life.
So if you want MPG, I would recommend something else. But if you plan on keeping the car 10+ years, I think this is a good air filter that could extend the life of the engine.

Good Deal
Great item and price, but crappy packing. They used a nice large box, stood an air filter up in one corner, and then filled the rest of the box with packing materials. Part did arrive undamaged, but could have easily been destroyed.

K&N drop in filter
I have really only been using the K&N for about 2-3K miles so far. I've noticed I can 'hear' the intake sucking air more with this air filter so I believe it when I read that it flows better. With higher air flow, I'll be curious to see how much the filtration decreases over a stock filter. My guess would be the filtration will suffer, but not horribly bad or in a dangerous way. Do not expect a huge HP increase with this filter, but I did get my best gas mileage after doing this filter, oil change, and spark plugs (37mpg HW).

In all I recommend this filter (so far) to anyone who plans on keeping their car for a while. With the cost of the filter and recharge kit, it is only saving you money if you plan on keeping your car for 90-120K miles after purchase of the filter.
