Upgrade Your Legacy 2.5i with Crawford Billet Power Blocks (BPB)

Crawford Performance Intake Manifold Spacers / Billet Power Blocks (BPB) for 2013 & 2014 Subaru Legacy 2.5i

  • Adds 15 HP / 22 TQ - No Tune Required

  • Improves Acceleration

  • Decreases Delay between Shifts with AT

  • Increases the Volumetric Efficiency of your Intake Manifold

  • Maximizes the Potential of Aftermarket Intakes

  • Installs in an Hour or Less

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 FB25 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, 8 longer mounting bolts, 4 Derlin o-ring seals, a stainless steel extended EGR tube, as well as an extended PCV hose. 
The install can be completed in under an hour, and is rated a 3 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 fuel. They are however not compatible with our Eco-Block, unless you are receiving a custom tune after install. 

Note: We only recommend this upgrade on naturally aspirated setups. 

Note: For Off-Road Use Only

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.
