Product Information
Cosworth Forged Piston Set 100mm Subaru WRX STI 2.6L EJ25 04+

The piston is one of the most important components within the engine. It can be subjected to directional change up to 285 times every second and must withstand acceleration forces of 8500g. Cosworth high performance forged pistons are designed and engineered to withstand this type of punishment and still perform. All Cosworth pistons are manufactured using the same methods as our Formula One pistons and include features such anti scuff skirt coating, ulta-strong pins, polished top and patented anti-detonation bands. Additionally, each application uses a unique forging to minimize weight and ensure the strongest possible piston design

- Unique forgings for each application
- Xylan Anti scuff skirt coating
- Polished tops (reduced carbon build up and stress relief)
- Manufactured from proprietary alloy (CosAl 010)
- Ultra strong pin
- Patented anti-detonation bands
- Bore size = 100mm
- 8.2:1 Compression ratio (nominal)
- Rings not included (use part number 20001515)
- For use with 81mm crankshaft

"High Quality Performance product"
TEXT_OF_5_STARS by Tauland
"I like it but if i have to choose right now i wasn't gonna choose Forge wintake just because -1 the relocation of the maf sensor -2 it should have been a clamp with something to hold on the stage 2 pipe same as the factory but its missing and all the system collapse and by that when u ecelerate it makes vibration noise cuz its touching the engine components. Final results:Very very good quality for a poor design."

"The customer service was great as usual. Just hate how difficult it is to contact DownforceUSA. Its better just to email them than call them directly. Visually, I'm very pleased with the carbon fiber lip. I just thought they provided the 3M tape and bolts/clips. I thought the install time would have take 10 minutes or less. I had to fiddle around and see if one of my OEM clips could work...sadly I didn't really find one. So going to the dealership was out of question. I picked up the tape and bolts from Ace hardware. I got it to work. I recommend having a friend help you out during installation. The quality of the lip was good but not great. The surface finish on some points was pretty bad. Most at least where hidden after installation. My big gripe, was the lip wasn't completely enclosed. Underneath, it was hallow. I wonder if this was for cost savings? This lip IMO would increase forward downforce but increased turbulence underneath. If your gonna scrape, I'd just buy the $50 FRP version as this one seems very fragile even though its carbon fiber."
