PPI's plug and play adjustable fuel pressure regulator for E8x/E9x 135i and 335i solves fuel delivery issues, low pressure issues, and lpfp pressure spikes and dips. Our regulator also aids the hpfp and stabilizes rail pressure.

Any 135i or 335i can gain from this but it's only necessary for cars making over 650 whp on E85.

We also offer a 6an Fuel Line Upgrade Kit, while this isn't required, it is highly recommended to use with our regulator.

Adjustable fuel regulator

Posted by Ryan Wazowski on Dec 11th 2021

Works great. This was easy to install and fixed all my lpfp issues. I have a PR stage 3 lpfp but still had low pressure. It was dropping to 50. After this I’m in the 80-90 psi range.
