JH Motorsports is pleased to now offer Cleaned, Flowed, and Resealed injectors for the 4.2L FSI!

Due to the continuously increasing amount of failing injectors that we are seeing, we decided it was necessary for us to get in front of this issue to be able to supply you with good injectors without having to pay the price of OEM Injectors. We recommend injector replacement as early as 80K miles based on data we have seen over the past years. It is wise to replace your injectors as they get older as failing to do so can lead to the destruction of your engine. When a failed (leaking) injector happens, it will end up taking out the entire cylinder, requiring a new engine.

The cleaned and flowed injectors you will receive go through rigorous cleaning and testing so they will run as good as a new set and much better than a used set. We have flowed and installed dozens of sets BEFORE cleaning at 1000 and 1700 psi and have found a consistent pattern of 20% to 30% variation in flow on almost every set BEFORE cleaning. We have flowed new injectors and they are within about 5% +- at best so that is the standard we use since we have yet to have an issue with brand new injectors. After repeated cleaning, testing and flowing we make sure all injectors are within 5% of the each other like we see with new injectors.

Core Charge:

The core charge is $480 ($60 per injector). Injectors will be assessed after they are received and checked for physical damage. We find that 1 in every 4 sets has a leaky injector which only shows up at those high pressures and running them through real world firing tests. 95% of the time we can recover leaky injectors with a tedious process. Since unrecoverable injectors are rare, we will not hold a bad injector against you. You will get your full core back as long as there is no physical damage to the injector or connector (including but not limited to broken off injector lock tab, cracked or damaged connector, gouged up from a pick to remove clips, etc).
