    Are they gapped correctly? Are they the right ones for your mods? do you have any mods?

    did you get all the plugs in properly and tight? did you get the packs bolted down tight? Did you remove intercooler, clamps tight? any cels? could be any number of things.

    I tightened everything down 10 fold but making sure not to over torque. I didnt remove my intercooler. The only think i had to move was my intake.by the way i have a perrin short ram intake and an hsk exhaust. Those are the only mods. I was told by the guys at the auto shot that iridium spark plugididnt have to be gaped.is this true?

    All plugs gap should be checked before you put them in, if someone happened to drop one it could mess with your engine. I'd pull them out just to be sure that's not the issue. But like said below, it could be a number of issues. Did you tighten your MAF back down after your removed your intake?
