Crawford BPB Intake Manifold Spacer
2013+ FR-S / BRZ / 86
Details
CNC machined from Billet 6061 aluminum, CP's BPB sandwich between the cylinder heads and the intake manifold to create longer intake runners. The lengthened intake runners enhance the volumetric efficiency of the engine which translated into an increase of 19 Horse Power, 15 Pound Feet of Torque and narrowed up the torque dip by 300RPM on a totally stock BRZ. Their Billet Power Blcok also works with any aftermarket tune, exhaust and intake components. Crawford's original road testing was done in conjunction with their stage 1 reflash followed by extensive dyno testing with and without a tune.
The BPB kit consists of 23 pieces that make it a complete bolt on system which can be installed in under 30 min. In the kit you will find 2 BPB, 4 Delrin O-rings, 11 mounting bolts, 1 nut, 4 fuel rail shield risers, and 1 support bracket for the direct injection control unit.
Anodized red.

A must upgrade after headers to eliminate the torque dip
By Sygfrid January 6, 2020This is 1 of the best engine upgrades I've done after the FT86 UEL headers & OFT tune for daily driving while keeping my FRS engine NA. The car now really pulls at around 3.2k rpm & the torque dip has been eliminated. You can regain the few lost top end by reprogramming the OFT tune as posted by Shiv on another forum. Even without a tune, you'll really notice a big difference on engine performance especially after the headers upgrade. My round TRD exhaust from 2019 TRD SE 86 sounds deeper & it does produce a pop as mentioned. Installation tips: It actually took us several hours to install it properly even if my mechanic's a pro since we took the necessary precaution of cleaning the dirt around manifold area to prevent vacuum leak. If you have an older car, REPLACE the original Intake Manifold Gasket that you can buy from Subaru. If you still experience some vacuum leakage after cleaning the manifold & replacing the gasket, try to reinstall by loosening the screws lightly & move & BPB around a little to help it settle in with the gasket.

Catches you off guard
By Oswaldo December 31, 2019I've seen cheaper alternatives elsewhere but still went with this one due to the fit and finish. With a little cussing, patience and a partner to help, it sealed very well. Definitely noticed some more passing power on the highway afterward.

Noticeable gains on butt dyno
By Stuart August 2, 2019This was a welcome addition to my CAI and engine back exhaust! I feel like I gained more than 19hp, possibly because of the combo making these even more efficient? On my 2018 BRZ the install was a little more difficult that expected mainly due to the position of the wiring harness but I was still able to install them on my own in about an hour and a half. I get some subtle popping sounds between gears now which is nice, and I swear the exhaust tone is deeper too.
