As said for the 100th time these are very paticular motors, orielly sells the MC wires nd plugs. Any thing else is hit and miss. Gap the plugs at .28". Same thing with pcv valves etc. Aftermarket ones just don't seal up, hell the factory ones don't either some times.best bet is get rid of pcv all together.
When I had the wick turned up on the turbo, around 18+ lbs, I gapped the plugs at around .018 to ,020. Worked good, especially at WOT
