B58 Gen1 DS3 HPFP Upgrade

After significant R&D, we’re proud to release the highest flowing single pump solution on the market, the DS3 (Dorch Stage 3)! This is our largest bore size and highest flowing pump to date, supporting incredible power with just a simple HPFP swap.  The DS3 is the same reliable, OEM drop-in solution you’re used to, but with 20% more fueling gains than our DS25! As usual with our kits, we have OEM hose routing for ZERO interference when changing out coil packs or spark plugs. There’s no cutting, no bending, no crimping, an included OEM quality high pressure line, etc. This kit drops right in with full control from the DME, just like factory. Combine this with our game changing injectors and one of our cam solutions and you’ll have never before seen, 4 digit direct-injection power!

Beyond the pump performance, why choose Dorch?

• PLUG AND PLAY: This is the ONLY true plug and play OEM fitment option on the market. Our kit includes our 250 bar capacity hardline to effortlessly connect our HPFP to your fuel rail (versus the time consuming process of bending and damaging the OEM line to fit).

• LIFETIME WARRANTY: The reason we can offer this is simply because our pumps are THAT reliable. That said, on the slim chance you have an issue, we’ve got your back!

• CUSTOMER SUPPORT: Ask around! It’s no secret that we offer unrivaled 24/7 support with REAL help. You’re an email away from professional engineers, technicians, and our tuner, who can solve anything you throw at them.

• TUNING SUPPORT: We aren’t just a hard part’s manufacturer. We have a dedicated calibration engineer in-house who painstakingly develops all of our HPFP files using OEM calibration tools and supports a global tuning network.
