K&N High-Flow Original Lifetime Universal Clamp-On Air Filter: Performance, Premium, Washable: Flange Diameter: 4 In, Filter Height: 5.5 In, Flange Length: 1.125 In, Shape: Round Tapered, RG-1001BL

Great filter, seems to be well made. My last filter worked for a couple years before it started falling apart on me. So far this k&n had given my camaro the extra zoom and more responsive on the highway. Also might need to put the shroud back. But my car does better without it for some reason. The rain doesn’t seem to get under the engine bay but I’m not driving over giant puddles of water either. Highly recommended if you want extra power to your car.

I have a cold air intake on my 2013 tacoma witch ends right behind my front grill. I use to have a cheap AutoZone filter and on a very rainy day My truck sucked in water and shut of on the freeway. After consulting with a handful of mechanics they all recommended to swap out the cheap cone filter with a K&n filter add an adjective to the fuel system and Wala, truck runs like nothing ever happen. It comes with plastic rubber spacers and a clap which fits perfect in my 2 inch intake pipe.

So I have a takeda intake for my 2012 Altima 2.5s. So the original takeda filter is over 60 bucks I can’t do that since I want to get a 2-3 of them. So I tried the spectre ones well they are not great I had issues that caused me to keep changing my maf sensor every few months due to the crappy filters spectre sells. So I had to back to a name brand. Well I can notice a better quality on these k&n filters. Yes it’s a close fit since I have an oversized battery. But will order two more when I can afford it. Great product. Why I want to order more since I clean one and let it dry I want to be able to drive my baby around

The media could not be loaded. Removed the rubber reducers and utilized the 4Inch, great snug fit and looks amazing

Not much to say here. Looks nice, works fine and received in good condition.

Typical k and n filter. Now I can hear the turbo whistle and much more affordable over stock replacement

I like this intake filter, but be careful to make sure it is compatible with your car before you get it. While technically it is a "universal" fit, check to see if your car's MAF (Mass Airflow Sensor) is attached to any of the parts you will be removing ( usually the original filter housing). If it is, you will need to buy a second part in addition to this filter, because the MAF is crucial when your car is calculating the proper air to fuel ratio. If the car can detect that the sensor is not working proper, then it will show a check engine light. However, if installed correctly, this K&N filter does increase performance and filtration.

I had an old cold air intake system on my truck (20 yrs.) and was concerned about what I would find to fit the intake pipe. But this filter has removal diameter duct sections to fit three different size pipes. So far so good hope this one lasts as long as the other one 159k!!
