I have a rjc megacooler with 3" pipe, 4" maf pipe, and a 70mm throttle body. Will need a spacer, for the intercooler pipe to clear the maf pipe? Thanks for any help!!:)
 
depends on your plenum and your turbo and you up pipe bend

smaller turbos make it real tight with 3" uppipe and the 4 maf pipes the

stock plenum , yes needs something, rjc AD plate helps a little but even with stock up pipe and 4" maf pipe its a snug fit

with PTE, mease i didnt need anything for 4" maf 3" uppipe and i have a little space between the pipes , no IAC angle adapter either .
accufab /KB was another story, they didnt angle the TB up like the PTE and their TB mounting flange is a little forward of the others so uppipe maf pipe clearance is very tight and iac gets really close (usually need to remove the connector cover with most 4" maf pipes and large turbos or go to an IAC angle boss like the BOPengineering

if you need spacers just call jack , www.cottonsperformance.com he has several alum spacer sizes instock .
 
Well I bought a 1/2" spacer and it fits great. But I do not have my hood on yet, it looks like it may not close.:eek: What do you guys think, will it close?
