3.75in to 2.5in reducer (z06 Maf)

[Whiteshadow]

Ive been looking up and down, i bought the z06 (~3.5in) Maf, but i cant find a reducer from 2.5-3.75in ANYWHERE...slowboy/extremepsi has em from 2.5-3.2 but that is for the 3in gm maf...can anyone point me in the right direction

Check out http://www.siliconeintakes.com/, they should have something that size, or very similar.

I used a silicone reducer that matched the size of my GM MAF (2.5" - 3") and shaved the inside of the coupler down a bit. Then I used a heat gun to heat it up, and then stretched it over the MAF.

Another method I've seen done is to grind the lip off the MAF.

2.5 to 3.5 will work... actually it'll work great since you want a tight/snug fit around the MAF lip, T-bolts afterwards and you'll never have issues of blowing pipes off under boost, (it happens, and it happens alot) I have the 3" MAF and a 3" reducer works great.

eBay has some good quality 4 ply silicone reducers, they're a bit pricey, also eBay has some cheap ones, but here you really will be very thankful you bought the nice ones instead. I believe extremepsi.com has some awesome reducers also.

Some link, but if you search more you'll find more
