SEAT Leon Cupra 290 Mk3 Turbo Blankets

Turbo Blankets are a simple but seriously effective addition to any boosted setup, whether your SEAT Leon Cupra 290 Mk3 is running a stock turbo or a bigger hybrid. A good turbo blanket helps keep exhaust heat inside the turbine housing, which can improve spool response and reduce under‑bonnet temperatures. That means less heat soak into your intake, hoses and wiring, plus a more stable base for further tuning and performance upgrades.

On a well looked after car you will feel the benefit most in repeated pulls or on track, where intake temps and engine bay heat can quickly creep up. Pair a quality Turbo Blankets with a decent intercooler, intake and exhaust system and you are building a much more efficient forced induction package, not chasing miracle power claims, just sensible, noticeable gains in consistency and drivability.

Fitment is straightforward for most setups, but it pays to choose proper motorsport-grade materials that can handle sustained high temperatures. Cheap, poorly made blankets can degrade, so we only list brands we would be happy to bolt onto our own workshop cars. Get the right blanket, install it securely, check for any oil leaks or contact points, and your SEAT Leon Cupra 290 Mk3 will be better prepared for hard road use or track abuse.
