CorkSport Fuel Pump Internals, CS HPFP Rebuild Kit, & OEM Fuel Pressure Relief Valve

The CorkSport Advantage

CS HPFP Internals

Give your Mazdaspeed the fuel it needs with the CorkSport HPFP internals! While the OEM internals do fine with regular driving on a stock car, they drop fuel pressure at higher RPMs with aggressive driving, especially with any engine modifications. The CS internals supply consistent & high fuel pressure, so you’re ready to make some horsepower! Check out the full listing linked above for full details.

CS HPFP Rebuild Kit

As these cars age, the seals within the OEM HPFP are wearing out, especially when running an ethanol mix. Prevent any issues down the road by replacing every seal in your HPFP with brand new E-85 safe o-rings from CorkSport. Check out the full listing linked above for full details.

OEM PRV

Failing pressure relief valves (PRVs) are becoming more and more common as the DISI MZR engine ages. When doing its job correctly, the PRV helps to control fuel pressure in the fuel rail. If your PRV is clogged or stuck open, you can have all sorts of issues, like inconsistent fuel pressure, misfires, check engine lights, etc. The included brand new OEM Mazda PRV will help you solve and/or avoid all of these issues!
