About this product

Part #: R-1040

K&N's Universal Air Filters are designed and manufactured for a wide variety of applications including racing vehicles, radio-controlled cars, generators, snowmobiles, tractors, and other applications. Regardless of the angle or offset diameter of the air intake, there is probably a K&N Universal air filter for your equipment. All filters are constructed with ultra-strong molded pliable rubber flanges which absorb vibration and allow for secure attachment and can also be stretched for up to 1/16 of an inch (1.5mm) to fit in-between sizes. K&N universal air filters are washable and reusable. When used as a replacement for the OEM air filter, modifications to the jetting may be required.

What made you choose this particular product?
The owner before me was responsible for installing this part, but from the HP gain K&N boasts and the fact that the OEM intake is bulky and unnecessary, I can see why he chose to do the swap.
Is this your first time buying from this brand? Did you consider other brands?
I've bought from K&N before and they've always been pretty top notch in my experience. I've also bought from Spectre, but this wasn't my choice so K&N it is.
Was it easy to install? Any installation tips that will help others?
I've taken it off multiple times to mess with other things and, yes, it is quite easy to remove and put back.

    Benefits of adding this mod

    A factory air intake system compromises your performance with restrictive tubing and low quality paper air filters. Upgrading to a wide breathing cold air intake optimized for delivering cooler, more dense air to your engine is the least expensive way to boost power and increase your fuel mileage. Take it a step further with our selection of forced induction turbos or superchargers to maximize your motor’s performance and breathe new life into your custom build.
