Deatschwerks Fuel Pump Hardwire Installation Kit dwFPHWK


Get the most out of your DW301 or other high flow fuel pump by ensuring it is getting the voltage it needs. Old, compromised OE wiring can limit the voltage your fuel pump receives.

We especially recommend this kit for use in cars over 10 years old, cars making over 400whp, and cars which were originally not designed for high horsepower. See Below for kit contents:

  • 15' of 12ga SLX spec red power cable
  • 5' of 12ga SLX spec black ground cable
  • 30 amp in-line fuse
  • 40 amp automotive relay
  • 4-lead relay socket with pigtails
  • Install instructions
  • DW window decal
Do you know what your intake manifold sits on?...a superheated boxer engine. If you don't know already, the cooler your intake air is the more HP your car will achieve. We present you the answer to this age old problem, raising the intake manifold off the engine with GrimmSpeed's™ new real Phenolic Intake Manifold/TGV to Engine Thermal Spacer.

Phenolic spacers have been used for years by many other specialized automotive companies, but this is very new technology to the Subaru world.

Grimmspeed Intake Manifold to TGV Gasket(Pair) 02+ WRX/STI/FXT/LGT Grimmspeed Up pipe to Turbo Gasket Grimmspeed Exhaust Manifold to Crossover Gasket(pair)
GrimmSpeed does it again! Introducting our enlarged bore Intake Manifold to TGV gaskets. Why do you want the enlarged bore style vs. the small oem?...the oem gasket hole diameter is much smaller than the TGV itself so you are very limited on matching up the ports of the outlet of the Int. Manifold going into the inlet of the TGV during porting. With our enlarged port gasket we are able to match the IM and TGV up perfectly which greatly improves air flow quality at a very important location in your intake track(right before it goes into the engine!). At GrimmSpeed we have worked with endless amounts of aftermarket gaskets, none seem to work as well as the multi-layer steel oem style gaskets. The issue with the oem gaskets from Subaru is that they are so expensive. Well Grimmspeed has your answer, a premium multi-layer steel w/ stainless steel fire-ring gasket at a great price.

Pair of GrimmSpeed TGV to engine gaskets. At GrimmSpeed we have worked with endless amounts of aftermarket gaskets, none seem to work as well as the multi-layer steel oem style gaskets. The issue with the oem gaskets from Subaru is that they are so expensive. Well Grimmspeed has your answer, a premium multi-layer steel w/ stainless steel fire-ring gasket at a great price. When it comes to wiring the Hella Horns that are mounted to your beautiful GrimmSpeed BroTie, we have you covered. After some testing, we determined that the additional few dBs offered by wiring with a relay weren't worth the added headache and potential failure points of a more complex harness using automotive relay, inline fuse and additional wiring directly to your battery. Fully pre-assembled, our simple harness will allow you to plug and play in seconds. Should your heart desire those last few ounces of ear-piercing goodness, our harness can also be adapted for use with a more complex relay harness. Diagrams for that configuration are included in our installation guide below.

Grimmspeed MAF Block Off Plate Subaru WRX/STi 08+ Grimmspeed T70 Torx Bit Grimmspeed Boost Control Solenoid - Subaru 08+WRX/05+LGT
When you upgrade your Subaru to a Blow Through System you will need a way to block off the location where the old MAF Sensor was located, well GrimmSpeed has the answer. GrimmSpeed MAF Block Off Plate allows you to do just that! Compact design that features black anodized aluminum for a very clean finish. We have taken it one step further and matched the bottom of the plug to the diameter of the Subaru intake piping so the plug is not in the way of flow!! The hard to find T70 Torx bit is needed to change the transmission fluid on the 04+ WRX, 03+ Legacy, and the 03+ Foresters. For the most part you can not find this at your local hardware store as they typically only carry up to T60 sized bits. So GrimmSpeed comes to the rescue!! Be sure to order one with your transmission cocktail so you have all the right tools you'd need to do the job.


Applications:

  • 03'-12' Forester X
  • 04'-05', 09' Forester XT
  • 03'-06' Legacy GT
  • 07' STI
  • 04'-10' WRX
GrimmSpeed is proud to provide the most complete and easy to use 3-Port Electronic Boost Solenoid for available for all turbo Subarus. Unlike your OEM 2-port solenoid, the GrimmSpeed BCS will allow for extremely high resolution boost control, providing your tuner with the hardware he needs to safely tune your car with rock solid boost levels. Using our solenoid, you are able to spool your turbo quicker and maintain tight control of boost levels throughout your power curve. In addition, our solenoid features a balanced valve to withstand up to 120psi without a slowing response by even a single millisecond.

Exhaust leaks seem to be an all-too-common issue with most modded Subarus. They tend to spring up out of nowhere and cause hours of troubleshooting headaches. The most guaranteed leak you will get though is if you run an aftermarket 3" downpipe to an OEM or OEM like 2.5" Exhaust. Compare our adapter to the competition and you will immediatly see why we offer the best solution to finally end that pesky leak.

Exhaust leaks seem to be an all-too-common issue with most modded Subarus. They tend to spring up out of nowhere and cause hours of troubleshooting headaches. One of the most common leaks that we hear about is from running an OEM downpipe with an aftermarket 3" catback without a proper adaptor. Use an adaptor that allows you to retain your stock donut gasket for the best solution to finally end that pesky leak.
The GrimmSpeed Air/Oil Separator for Subaru vehicles has a unique patent pending design that allows you to maintain your PCV Valve while separating the oil out of the crankcase and head ventilation air! Our AOS will allow your engine to run more efficiently due to the separation of oil from the intake system. When there is oil in your system, the result is 1) reduced fuel octane 2) higher chance of engine knock(detonation) 3) worse emissions 4) higher oil consumption. Our Air/Oil Separator will help all of these problems.

You probably already know that you want an intercooler with maximum cooling and minimum restriction, but when it comes to selecting the right 'man for the job',  we think it's important to understand why. As air is pressurized by your turbo, it heats up, not because of the heat of the turbocharger, but because when they're compressed, the atoms in the air are forced closer together and as a result, move faster and have more energy. That energy manifests itself as heat. The more heat we can remove from the system, the denser the air becomes and that's what helps eliminate pre-detonation, or 'knock', allowing for increased output from your system. Your OEM TMIC does just fine at stock boost under normal use, but as soon as you start putting some real heat into it with higher boost or harder use, it heat-soaks beyond recovery.

Grimmspeed Master Cylinder Brace - Subaru LegacyGT 05-mid 07  NON-VDC Grimmspeed Turbo Heat Shield Grimmspeed Turbo Heat Shield w/ Black Ceramic Coating
Crafted from hardcore CNC laser cut 12L14 with multi-point welded fabrication. It is the Abrams Tank of master cylinder braces touting 4 factory mounting points, the most available from any brace. Powdercoated black this brace will outlive your car and win you some style points to boot. Most importantly this brace kit will kill your wimpy pedal feel and give you the immediate and tight response that your performance car deserves and needs when you hit the track or rally. This brace will give you the confidence similar to that of SS braided brake lines with precision stopping. Not to mention street driving just got a whole lot more fun! We knew when it came time to design this product we didn't want to just create another heat shield to add to the mix, but create another level of product. The basic heat shield would not cut it, we wanted every fitment of turbo, downpipe, and up pipe combination we could work into one design. We measured, cut, bent, welded, riveted, and after many tested prototypes we arrived at a heatshield we are extremely proud of. Other heatshields had problems with cracking, poor fitment, or poor heat coverage but we would not settle for this! So here it is, elegantly simple in style, but painstakingly engineered in design. It's what you can expect from GrimmSpeed.
