Direct fit for the GM trucks. I was using them for my STS kit, but now I am blown and dont need them any more. They were from Nelsons and have about 9 months on them now.

$250 Shipped.

 

what kind of h.p can i pick up with these? how bad does it hurt fuel economy? can they be installed by me or is it complicated than i need a professional mechanic to install?

 

They are primarly for boosted applications: .i.e STS kit or whipple.

There is no direct gain, they will provide additional flow needed to keep up with boosted applications. They need to be installed into the fuel rail/intake manifold, then the tune needs to be changed to compensate for the additional flow capacity.

 

Ill take them!

 

Sale Pending.
