Naturally Aspirated (N/A) vehicles are starving for air without a turbo. Sure, an aftermarket Intake / Cold-Air Intake will bring more air in, but without a bigger volume in your intake manifold to receive the extra air, the air flow essentially gets choked before it has a chance to enter the engine.
The Crawford Billet Power Blocks raise your intake manifold, lengthening the intake runners. This increases the volumetric efficiency of your manifold, which provides optimum airflow so that your engine receives as much air as your intake (OEM or aftermarket) can throw at it.
Tested on and off our Dynapack Chassis Dyno, we stacked plates up then back down until we found the sweet spot that makes your FB20 engine scream (in a good way)!
Made from CNC'd billet 6061 Aluminum and anodized red, these spacers look incredible under the hood. The kit includes the 2 spacers, 6 longer mounting bolts, 4 Viton 75 o-ring seals, a stainless steel extended EGR tube, as well as an extended PCV hose.
The install can be completed within 3 hours, and is rated a 6 out of 10 on install difficulty.
We recommend running mid-grade or premium fuel for the best results.
The BPB's are compatible with OEM or aftermarket intakes, tunes, and higher octane fuels.
Note: We only recommend this upgrade on naturally aspirated setups.
If your vehicle has high mileage (~100,000 miles), consider purchasing set of new Intake Manifold Gaskets with your order. If you reassemble your vehicle after installing the BPB's and receive CEL Code P050A, an air leak from your gaskets is most likely the cause.
