Without reliable dyno data it is really hard to choose a kit from the assorted manufacturers. They all have high claims and have their data to confirm it, I find them all subjective. I decided I would pick a kit with the following items:
The intake I chose is from Street Smart Design. The kit comes complete with the K&N filter and recharge kit. Unlike most aftermarket kits, this one kept the air intake at the fender, where the rest pulled air from inside the engine compartment. The intake went on in a half hour.
When I first installed the kit I didn't like the way the wires were exposed in the maf connector. Since that time I was able to slide down the rubber grommet to cover the wires.
