The SpeedFactory Racing Billet B-Series Crankcase Pressure Port Fitting precisely monitors Honda/Acura B-Series engine crankcase pressure levels, with a 1/8” NPT pressure sensor ideal for turbocharged cars. Crafted from 6061-T6 billet aluminum for strength and durability, the black anodized finish prevents corrosion for long-lasting use. Dual O-rings form a secure, leak-free seal and dampen vibrations while an integrated 1/8” NPT pressure sensor port provides accurate readings. Moreover, the 17mm wrench provision simplifies installation. Honda Bond lubrication and bonding is recommended after cleaning the block and fitting with brake cleaner for a secure connection even under high crankcase pressure.
