Engine Covers

Engine Covers: dress the bay, protect the top of the motor

An engine cover sits over the top of the motor or, on a V-twin, over the primary and cam areas. Some are functional plates that shield wiring, plumbing and moving parts; many are cosmetic panels that clean up the look of a crowded bay or replace a factory plastic shroud with carbon fiber or polished metal. Whichever job you want done, the engine covers here span both worlds, from track-focused dry carbon panels to chrome primary covers for cruisers.

What ThreePiece stocks

There are 58 engine covers in this category, spanning 10 brands. The biggest ranges come from Kuryakyn (19) and Perrin Performance (18), followed by HKS (6), COBB (5) and Bikers Choice (4), with Kartboy, Performance Machine, TwinPower, Seibon and Wehrli filling out the rest. Prices currently run from $39 to $1,448 — that's the live range on what's in stock now, not a fixed quote.

Fitment data is attached to 43 of the products, with model years spanning 1970 to 2024. The most common makes are Subaru, Toyota, Harley-Davidson, Nissan, Volkswagen, Audi and Honda, and top vehicles include the Subaru WRX and WRX STi, Toyota GR86, Subaru BRZ, Nissan Z, Toyota GR Corolla, Volkswagen Golf R and several Harley-Davidson Touring, Softail, FLST and FXDWG platforms.

How to choose

Two broad buyer paths run through this category. For sport-compact owners chasing a lighter, cleaner bay, the dry carbon route is the top of the price ladder — the HKS Dry Carbon Engine Cover for the A90 RZ and the HKS Civic Type R FL5/FK8 carbon cover sit near the top, while the Seibon carbon fiber cover for the 2023+ Nissan Z is a similar idea for the Z.

For V-twin riders, the covers are about finish and coverage over the primary and cam areas: the Performance Machine Vision Cam Cover in contrast cut, the Bikers Choice chrome outer primary cover for 99-06 Touring and the Bikers Choice chrome primary cover for FLST and FXDWG are examples. The trade-off is straightforward: carbon panels buy you weight savings and a bare-bay look, chrome and machined covers buy you finish and a specific model fit. Match the cover to your exact year and platform first, then decide on finish.

What else you may need

Covers often come off during other top-end work, so it's worth pairing this browse with the rest of Engine Components. If you're already in the motor, look at Head Gaskets and Gasket Kits for reseal work, plus Oil Filters and Radiators for routine service around the same job.
