About this product

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.

What made you choose this particular product?
My first mod ever to my FRS.
Is this your first time buying from this brand? Did you consider other brands?
I actually went through the forums to find the best filter... the difference was only a couple hp/lb-ft of torque but I was a noob at the time.
Was it easy to install? Any installation tips that will help others?
Despite never having worked on a car it was quite straight forward.
Once you've had a chance to use the product, did it meet your expectations?
My butt dyno totally felt it.
Any additional comments?
I would prefer a dry filter from now on. Just trying to wiggle it in is a pain if it gets all over your hands.

What made you choose this particular product?
I needed a replacement for my mechanical fuel pump that sprung a leak and decided to go electric to update the fuel system a little.
Is this your first time buying from this brand? Did you consider other brands?
I've bought air filters before but this is the first fuel pump.
Was it easy to install? Any installation tips that will help others?
The installation was pretty simple. The hardest part for me was finding a mounting spot.
Once you've had a chance to use the product, did it meet your expectations?
It's worked great for me so far.

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.
