Mishimoto MMHOSE-SUB-ITBBK Subaru WRX Silicone Throttle Body Hose, 2008+, Black

great fit nice and soft. great product

Fit like a glove and a strong improvement in feel over the stock one. No performance gains with this one, just the assurance that it will mot blow out, as the stock one at 135k is hardened and starting to split. Great update! No trimming! Just remove and install.

Not only was the stock hose leaking oil, Subaru Canada wanted an arm and a leg to replace it with a stock hose. The Mishimoto hose was 1/3 the quoted price and fit like a glove. Installation took about 45 minutes. Note - be sure to have plenty of light available as the bottom clamp is nearly impossible to see because it is buried under several other hoses... Power delivery is better now, and lag has been greatly reduced (your results may differ, my stock hose was leaking and robbing my car of low RPM power).

Super easy to install, good quality product!I've been hunting a hesitation issue in low RPM's for quite some time and after some research, it is known for our factory throttle body hoses to deteriorate overtime.After removing my intercooler and inspecting the factory hose, it is clear to see the cracks and tears that has developed over the years through heat cycling.Once installed, I didn't bother resetting my ECU and decided to let the car relearn it self. Hesitation was still there but after several days of driving, it is almost 100% gone!Just a tip, the hose is quite tough and rigid out of the box so please make sure to re-tighten your hose clamps after several days of driving as the clamps will loosen. This could be due to vibrations or the silicone hose becoming a little bit more flexible through heat cycles. I've also relocated the location of the clamp on the throttle body so I can re-tighten without removing the intercooler. A socket extension can reach between the intake manifolds to the bottom of the throttle body.

This IS the fix for the 08-14 WRX intercooler to throttle body hose fix as the JUNK stock subaru one is a failure from the factory big time. Especially pushing more boost then stock its a must!!I'll be honest here, it was a damn struggle to get the Mishimoto one on as alot of people have said. But, there's definitely a trick to it as it has to put on exactly with the dimple inside the hose exactly on the bottom or it will not work for you. Lube up the inside lip with spit and put it on the throttle body first semi loose on the clamp, then loosly bolt the intercooler to the turbo so it stick can move a bit (don't forget grey anti seize on the bolts) then lub the inside lip of the hose on the intercooler side and muscle it into place. Then crank down both clamps. Then the bolts on the turbo.Mine seats 100% in both ends. Fit, finish and durability is 1000x better then the stock junk hose.The people here that can't get it on are doing it wrong. Follow what I said here and it WILL work for you.Or message me and I'll show you more pics of how to do it right.
