About Engine Parts

Chasing more boost, or keeping a built motor happy? That's the split on this page. The boost side runs from a charge pipe all the way up to a whole turbo. The other side is what keeps a modified engine cool and planted, so it's still around for the next track day. Save your car and you'll never get shown an intercooler cut for a Golf R when you drive an Accord.

Order matters more on this page than anywhere else on the site. An intercooler before a tune buys consistency on a hot afternoon and almost no peak power. A bigger turbo before fueling buys a light on the dash. Every listing says what it needs beside it, and it's blunt about the parts that do nothing until something else goes on.

Heat is what these cars actually fight. A factory core on a WRX soaks after a couple of hard pulls and the ECU starts pulling timing to save itself. That's why the cooling parts sit next to the turbo parts instead of in some accessories bin. Stiffer mounts belong here too, because that's how you stop the shifter dancing on a launch.

Common questions

Do I need a tune for engine parts

For anything that changes airflow or boost, yes. Intercoolers, charge pipes and catch cans are happy on the factory map because they don't change how much air gets in, only how hot it arrives. A bigger turbo or a boost raising pulley wants fuel and timing sorted first, and each listing tells you which side of that line it sits on.

What does a catch can actually do

It traps oil vapor from the crankcase vent before that vapor reaches your intake. On a direct injection engine there's no fuel spray washing the back of the valves, so it bakes on as carbon and you quietly lose power over the years. Empty the can at every oil change and it's maintenance rather than a modification.

Are stiffer mounts worth it on a daily

A street insert, yes. A solid mount, no. The insert fills the voids in the factory rubber and stops the engine rocking under load, which is what makes a shift feel vague. You'll pick up a bit of buzz at idle. A race mount sends all of it into the cabin and belongs under a car that lives at a track.
