We have tried nearly every intake option on the market. And we can say without a doubt the Plazmaman intake manifold came out on top. You can find them here.
Intake options are:
Great intake manifold, easy bolt on and come with a range of different throttle body options and are available to suit P11 & P12 heads. These are setup for full length 14mm injectors.
Great intake for the budget build, these use the standard lower runners.
