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.
All of our products comes with a Limited Lifetime warranty.
