what is the best intake manifold

[gottaluvg8]

Hi i am new to this forum and i was wondering what everyone is running for intake on there 6.0 g8 gt modded motor. i want to get a different intake but i have read alot on the fast 102 intake and for the power gains you get im not sure if i want to spend the money. the motor it would go on has a cam ported and polished heads 1 7/8 obx headers with high flow cats, with a roto fab cold air intake the tb and intake on the motor right now are ported and polished i was just wanting seeing what people are running on there cars thanks

Get the RickCrawford modified intake, better than the FAST and cheaper.

Back to back tests have proven Ricks intake manifold is superior unless running a shit ton of boost. The difference when I put just that and his TB port on my GT was VERY noticeable with no tune change. My GXP has both as well.

ok that is what is on the car right now. it also has a rcr ported and polished tb. have any of you had problems with your car setting a p0507 where the car idles in park at around 1000 rpm any ideas on how to solve this.

Sounds like it could be a vacuum leak.

The engine is VERY sensitive to any leak so check ALL the fittings including the brake booster line on the rear.
