Review on 🔌 Silicone Throttle Body Hose for Subaru WRX 2008-2014 - Mishimoto MMHOSE-SUB-ITBBK (Black) by Eric Surabhi

Very easy to install, good quality product! I've been looking for a low RPM problem for quite some time. and after some research our factory throttle body hoses have been known to wear out over time. I didn't bother resetting my ECU and decided to let the car relearn. There were still fluctuations, but after a few days of driving they were almost 100% gone! Just a tip, the hose is quite stiff and stiff out of the box so please remember to retighten the hose clamps after a few days of riding as the clamps will loosen. This can be due to vibrations or the fact that the silicone hose has become a little more flexible due to temperature changes. I also changed the position of the clamp on the throttle body so I can re-tighten it without removing the intercooler. The pipe extension may extend between the intake manifolds to the bottom of the throttle body.
