As these cars get older we're seeing more issues with the stock components and more demand for cost-conscious fueling solutions. The new Fuel-It 650HP line of fuel system upgrades are designed with those needs in mind while maintaining a budget. They make the most of the stock components to maintain stock reliability and drive-ability but when the boost gets cranked up, the Fuel-it 650HP components kick in to support the additional fueling needs of your high horsepower car. With the Fuel-It 650HP lineup, you can upgrade your components all at one time or upgrade them as time and budget allows. If upgrading one component at a time, we'd recommend starting with the LPFP first as that is the heart of your fuel system, without a good Low Pressure Fuel pump (LPFP) you can't supply the fuel needed to any of your other components. Your secondary pump can NOT run full time, it must only be run under boost only. Running it full time will place additional strain on the stock system, will lead to high fuel temps, and pump or component failure. To turn the secondary pump on under boost we recommend running the included 4psi Hobb's switch. Included with all S65 LPFP upgrades: Walbro 450 pump (F90000274) Black Anodized Custom fitting Pump brackets 9/64" terminals and associated hardware Fuel line Replacement PITA clip Wiring harness

VTT is proud to announce the S65 Billet Valve cover set. VTT created these for the S65 owner who wants to add a great look to their engine bay while also getting rid of the stock valve cover which are very problematic and can crack/leak/delaminate with higher mileage.

The internal baffling is 100% in place to knock down any oil from the vapors before being expelled. Factory PCV has also been kept in place so these can be run in essentially any configuration required. 100% CNC 6061-T6 Aircraft aluminum construction Anodized in a variety of colors Lightweight; 9.7 lbs. (compared to 7.9 lbs for a stock cover – only 1.8 lbs difference) TWO shrouded -10 ORB ports which Give the end-user variety for setting up their Valve Cover and PCV System Only Billet option on the market with a threaded oil cap, and PCV choices Works with our 1' one-way breather for ultimate crankcase venting Kit includes: Two Billet Valve covers Two US-sourced Viton Gaskets
