It fits 2004.5-2014 STI models with drive by wire TB. Our 75 MM throttle body comes as a kit including stock manifold adaptor plate and 60 MM hose adaptor (for those that want to use it immediately with stock intake pipes). The kit also includes 75 MM hose adaptor and all mounting hardware. Throttle bodies are CNC machined of billet aluminum. Parts are available in natural aluminum, red, blue and black anodized finishes. Increasing the diameter to 75 MM gives almost 56% increase in throttle cross section area over the stock throttle body. Replacing stock throttle body with our new 75 MM (even with stock pipes and turbo) will give you a few additional HPs and greatly improve engine response. Replacing the stock throttle body with our 75 MM throttle body and replacing intake piping with larger diameter (75 MM) gives limitless possibilities of increasing engine power. All parts are manufactured to our legendary high quality standards and backed up by our warranty.

Very nicely constructed product. Installed it moments after I took delivery of it. Tuning went smooth with it and now making some nice power. Very disappointed that you have to purchase the 3" adapter. It's a 3" throttle body it should come with it. If you want to run it on a stock set up you should have to buy it for that.
