More power, great looks, more consistent performance and no downside by upgrading to the Dinan High Performance Intercoolers for the N63TU V8. Heat is the enemy of horsepower, beat it by replacing the air-to-water intercoolers with larger units from Dinan to reduce the charge air temperature. Add an impressive 23 horsepower and 15 lb-ft of torque when used with the DINANTRONICS™ Performance Tuner and Dinan exhaust. This additional cooling is even more important in hot climates where the inherent power loss is much higher.
The two intercoolers are beautiful and purposeful looking, wrapped in black powder coat and laser engraved with the Dinan® logo.

+ Replaces factory air-to-water intercoolers with 23% larger units.+ Black powder coated and laser engraved intercoolers.+ Includes silicone hoses, coolant lines, mounting brackets and hardware.+ Maximum gain of +23 hp and +15 ft-lbs (when used together with the DINANTRONICS™ Stage 3 Performance Tuner as well as Dinan exhaust)
DINANTRONICS™ Performance Tuner (D440-1604-ST1 & D440-1604-ST3): The DINANTRONICS™™ Performance Tuner is a highly engineered and sophisticated piece of computer hardware and software that enhances engine performance, without negating or voiding your new car warranty coverage and without affecting long term reliability or the functionality of on-board diagnostic systems. It is also the only tuning device emissions legal in all 50 states. The ultimate objective of developing this piece of technology was to provide the ability to control every signal entering and exiting the BMW factory Engine Control Unit. These items are unique to Dinan and together they embody the apex of performance engineering in a powerful, reliable, and warrantied package.
Free Flow Stainless Exhaust (D660-0040 & D660-0040-BLK): Dinan's Free Flow Exhaust improves exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be and pleasantly aggressive under harder acceleration with zero drone. 100% stainless steel construction and exacting specifications ensure that the system fits correctly using the factory hangers and will resist corrosion for years to come. An vacuum controlled butterfly valve is utilized to improve flow at wide open throttle while keeping things civilized and "drone" free throughout. The design reduces overall weight as well and features 3.5'' black ceramic coated tips for a tasteful high performance look.
