"We feel that the Crawford Performance Power Blocks intake manifold spacer makes the largest non forced induction power gain of any single part we have tried to date."
          - MotoIQ 

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 FA20 engine scream (in a good way)! 
Made from CNC'd Aluminum and anodized red, these spacers look incredible under the hood. The kit includes the 2 spacers, 4 Block Standoffs, 10 longer mounting bolts, 6 washers, 4 Derlin o-ring seals, a grounding bracket for the direct injection control unit and the nut/bolt to mount, as well as an extended PCV hose and fitting. 
The install can be completed in under an hour, and is rated a 3 out of 10 on install difficulty. 

If you choose to use E85 with our BPB's then you will see a larger increase in power and torque than if using pump gas. 

The BPB's are compatible with OEM or aftermarket intakes, tunes, and fuel. 

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.

A set of these gaskets come in our Short Block installation Kits, but are also a good idea to replace when installing our Billet Power Blocks (BPB's) while the manifold is disconnected. These are silicone gaskets, so they are reusable if not dry/cracked or deformed. If your gaskets don't look fresh, grab a set of these to install with your new BPB's.
