No need to risk leaks with old, worn radiator hoses.
GrimmSpeed Radiator Hose Kits use multi ply reinforced silicone to handle heat and pressure far better than aging OEM rubber. Built for consistent coolant flow when things get pushed.
Available for a wide range of WRX, STI, Forester XT, and Impreza fitments. Finished in red or black to match your setup.
Our V2 Turbo Inlet for the 2015â2021 WRX is now officially patented.
This one means a lot. It represents the incredible time and effort that goes into every design we put our name on.
From the ground up, this wasnât just about making a stronger replacement. It was about rethinking the shape to create a smooth, lofted internal path that promotes clean airflow and reduces turbulence. That level of detail is what earned this design patent, and itâs a clear signal of where weâre headed:
More original designs. More innovation. More parts that push the platform forward.
Factory charge pipe holding things back? Time to fix it.
GrimmSpeed Charge Pipe Kits open up airflow with larger diameter aluminum piping and smoother transitions from turbo to intercooler.
VA or VB, this is how you improve airflow. Available in Red or Black.
This is what a proper shift should feel like.
@cwp_sti20 âs STI will find it hard to miss a gear with the GrimmSpeed Short Throw Shifter installed.
Less travel. More control. Zero slop. Just clean, precise engagement every single time you shift. Built with Enduro MAX ball bearings for ridiculously smooth engagement and the kind of precision your stock setup just canât touch.
It only makes sense that GrimmSpeed employees drive Subarus. Chris M gets to and from work in his 2022 VB WRX. In this video he will showoff some of his upgrades and talk about what he plans to do next to build more power.
Follow Chris! @slow_wrx37
Shoutout to @j.hanth for sharing this video.
He has our GrimmSpeed Unequal Length Exhaust Header bolted up and can't help but start the car to hear how it sounds. Although this doesn't feature our GS Catback, you can still clearly hear the difference the Unequal Length makes to the exhaust note.
Top Mount or Front MountâŚ
We build both intercoolers for a reason.
TMIC: short path, fast response, perfect for street-driven setups that still mean business.
FMIC: larger core, direct airflow, built to handle heat when the power goals climb.
Different layouts. Same goal. Unbeatable performance.
So what are you running?
Whether choosing our VA or VB Equal Length Headers, you can't beat the quality. Which one is right for you?
Equal Length design means consistent exhaust flow into the turbo which translates to better response and a more controlled powerband. Built right and SEMA certified.
First CARB EO. Big moment for GrimmSpeed.
The GrimmSpeed 2-Bolt Up-Pipe for EJ25 just secured its official CARB Executive Order #D-895, marking a huge step forward in emissions compliance without compromising performance.
This isnât just another approval⌠itâs GrimmSpeedâs first CARB certification, and it sets the tone for whatâs coming next. This is just the start!
