Review on 🔴 Mishimoto MMHOSE-SUB-ITBRD Silicone Throttle Body Hose for Subaru WRX 2008-2014 Red - High-Quality Replacement Part by Ayush Bonuccelli

Very easy to install, good quality product! I've been looking for a low rpm problem for quite some time and after doing some research it's known that our factory throttle hoses wear out over time. After removing my intercooler and inspecting the factory hose, you can clearly see the cracks and fissures that have developed over the years from the heat cycling. After installation I did not reset my ECU and decided to let the car learn again. 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.
