2008-2014 Subaru STI Interior Parts

The Shifter Is the One You Feel Most

On a six-speed STI, the shifter does all the heavy lifting. It’s also the first thing to wear down. 

A Subaru STI shifter knob upgrade changes gear changes immediately. Weight is the main variable: a heavier knob adds momentum that smooths the throw and makes shifts feel more deliberate, while a lighter one keeps things quick. Perrin makes some of the most popular Subaru STI shifter knob options on this platform for exactly that reason, in a range of weights, finishes, and thread pitches.

Pair it with a fresh shift boot if yours is cracked, and the whole console will read as newer. Go further with a short shifter and shifter bushings, and the drivetrain feel tightens up completely: less slop, shorter throws, and more precision.

One thing to check before ordering: thread pitch varies between five-speed and six-speed transmissions in these years. Filter by your exact car with our Garage tool rather than guessing. 

Lighting, Trim, and the Small Fixes

After the shifter, it’s the details that separate a tired 2008 STI interior from a sorted one.

Morimoto LED bulbs are the cheapest transformation available. The factory dome, map, and trunk lights on these cars are dim and yellowed by now. Swap them, and the cabin instantly reads a decade newer, with no flicker or error codes. Footwell and ambient lighting take it further if you want the modern look after dark.

Perrin pedal sets add grip for heel-toe work and clean up a set worn smooth. JDMuscle trim pieces and accents tie the cabin into the rest of the build. Custom floor liners handle winters that factory carpet gave up on years ago.

And for the things that simply broke: Subaru OEM parts cover the clips, panels, and console pieces that go missing on fifteen-year-old cars, factory-correct rather than approximated.
