Excellent upgrade for 2015-21 WRX
ETS is absolutely the go to FMIC for 15-21 WRX’s along with every other make and model car. Key things to take into consideration if you’re on the fence about switching from a TMIC to FMIC is not only does an FMIC upgrade significantly lower intake temp and maintain those temps, it also cuts out having to remove the TMIC which reduces maintenance and service times and allows for the most part instant access to behind the engine and top of the transmission and ETS has superior craftsmanship and quality components. For the 15-21 WRX, having a FMIC allows for easier maintenance and service period. It cuts down on time to remove the intake manifold, allows easy access to the PCV which allows for on the go IAG AOS check valve replacement along with inspecting or replacing the plumbing associated with the IAG AOS, spark plugs and coils packs are easier to access, the list goes on for anything that requires removing the TMIC and charge pipe to perform maintenance. Removing the charge pipe, especially a Killer B charge pipe and aftermarket top mount to do a lot of projects on my car has been the only thing I don’t like to do simply because it opens up the possibility of making a mistake connecting a coupling, mainly the top mount to throttle body coupling. ETS is the way to go simply because the kit includes T-clamps while competitors are mostly using worm gear clamps. All of the components in the kit are top notch and designed to last and allow for headroom for adding power in the future. Since I have an upgraded turbo I went with the 3.5 inch core, the 3 inch would be more than sufficient but I plan on keeping my car and eventually getting a long block then turning up the power. Managing heat along with keeping up with maintenance is the key to boxer engine longevity, the FMIC will allow me to use the TMIC location for an oil cooler when I eventually opt for a long block. I highly recommend ETS, I’m going to replace my intake with an ETS intake because that’s well designed as well. Anyone with an upgraded turbo should really make the switch to drop the intake temperature because even though a quality top mount can manage the temperature, it’ll eventually heat soak due to location but the upgraded turbo will spool much quicker, compressing the air which on its own raises the temperature to the degree that a top mount can’t keep up with even with plenty of air passing through it.
