Modified Air Intake

Does anyone have any pic to show?. Here's mine. On the dyno it was worth 9 hp.

Looks like he broke off the stock nexked down part of the air box where it goes into the rubber boot. Then plastic welded a piece of 3 or 4 inch round PVC to it.

You're Right. It makes the neck a full round 3in opening. On the dyno it showed 9hp gain without tuning.

Good job! Ive thought about doing the same. Ive seen something similar done. The stock design is good just restrictive.

Good gain..How did you do it? How do you weld plastic? I thought about raising the roof also. I think i would have room with the ss hood. If not cuting and refiberglassing the area.

How do you get around the MAF, if possible?

I was thinking about using the holes where the fog lights are to route the air intake to the filter and then into the plenum
