When I bought my '92 240SX coupe over a year ago I picked up a used Injen air intake tube with a Matrix air filter. The intake was off a car that had been in a slight accident so it had a nice dent in it and was scratched up. I took it home and sanded it down then put a few coats of gloss grey engine enamel (with ceramic) on it and in it. Then I installed it. Drive it around for 1 day and I thought it made the engine bog really bad so I pulled it off and reinstalled the stock stuff.

Later I came here to Zilvia.net to discuss my findings and some people said "yeah the Injen intake will make the engine bog" and others said "don't give up so easily, reset your computer and you will feel gains from the intake." At that point I decided I didn't want to deal with it and I put the Injen on a shelf where it is still collecting dust today. I've often wondered if I put it back on and reset the computer to adjust to the added air if I would like it, but I just didn't wanna bother with it.

This week as I was working on my car I decided to remove the resonator box from beneath my stock air box. Little did I know that this thing was just a closed box, I thought it was a box with an opening that actually pulled in air. So I tossed that thing aside, then I started looking at what I had here. I then got some scrap pieces of 2" ABS pipe and found that a piece of it fits snugly into the plastic piece that use to attach to the resonator box. So I cut a piece about 8" long and using ABS glue glued it to the piece. Then I used a piece of rubber from a pipe coupler and put that in the hole through the sheetmetal so that the new pipe would not rattle in the hole. Then I removed the vent off the front bumper and reached in and glued a 90 degree ABS 2" elbow to the pipe sticking down, facing the elbow straight towards the vent in the bumper. Not thinking that was good enough I then put a 2" to 4" ABS coupler on the elbow so that it could pick up more air.

Took it for a test drive and you could hear the intake better than stock, but not as loud as the Injen (I prefer louder) but I could definitely tell a difference in performance according to my seat of the pants dyno.

Cost in parts: $0.00 since I had them all laying around, but wouldn't cost more than $10.00
