We all know how bad the OEM Subaru Top Mount Intercooler Gaskets are. They are the greatest source of leaks in the entire intake stream. Fear not, GrimmSpeed has answered your call! We present to you the 3x thicker GrimmSpeed TMIC BOV Gasket. Not only is this gasket 3 times thicker, it also contains an inner metal layer that will help prevent blow outs. The TMIC surface and the BOV flange never seem to truly mate to each other. That's where the 3x thicker BOV Gasket's extra thickness comes in handy, creating a better seal for better protection against leaks.

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. Grimmspeed's engineers overlaid 3D scans of GD, GR and VA chassis core support in CAD. From there, a unique design was created that allows the same bracket to work on all supported models. This means that should to change cars, your BroTie can stay by your side. Also incorporated are three long mounting slots on each side, for maximum adjustability. This allows you to place the horns in a number of different configurations, depending on your grill and personal preference. 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.

In addition, our solenoid features a balanced valve to withstand up to 120psi without a slowing response by even a single millisecond. For years you've been asking for intakes, and for years Grimmspeed silently worked to create a solution that sets itself apart from the rest. We examined and tested current offerings, and identified their shortcomings. We formed theories, and over months of testing designs we proved them. Combined with our advanced research and development program, we fully utilized our engineering resources to design and manufacture what we believe is the most comprehensive intake solution available for the 2008-2014 Subaru WRX and STI and the 2009-2013 Forester XT.

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.

So, 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 Impreza/WRX/Sti 08+ Subaru Legacy/GT 08-09 Grimmspeed Turbo Heat Shield Grimmspeed Turbo Heat Shield w/ Black Ceramic Coating
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.

These have both been a long time in the making and as the popularity of GrimmSpeed intercooler offerings has skyrocketed, we've had a massive amount of demand for splitter options that maximize performance of our Top Mount Intercooler on the 08-14 STI platform, with some users producing 600-700whp with them.
