Uprated Water-to-Air Charge Air Coolers for BMW E70 X5 50i and E71 X6 50i

Unlock dependable, repeatable performance from your twin turbo eight-cylinder with this pair of Dinan water-to-air charge air coolers. Engineered for the N63B44 in the E70 X5 50i and E71 X6 50i, these uprated heat exchangers slash intake air temperatures, curb heat soak and keep power delivery strong during spirited driving, motorway pulls and warm weather use.

We run these units on customer cars at MJ Modifications and the results speak for themselves. Lower IATs, crisper throttle response and consistent acceleration run after run. Combine the coolers with the matching Dinan calibration and expect gains of up to 20 bhp and 10 lb ft alongside improved consistency.
