It do88 Chargecooler intake manifold for vehicles with the BMW B58 Gen 1 engine combines an aluminium intake manifold with an integrated air-to-water charge coolerThe system has been developed as a replacement for the original plastic intake manifold and is designed for easy installation without modifications.
The system uses a 102 mm (4") Bar&Plate charge cooler core, cast end tanks, a thermal insulation spacer, and integrated connection options for supplementary fuel injection, methanol injection, nitrous oxide injection, and measuring equipment. During development, 3D scanning, CFD analysis, 3D printing, and SolidWorks simulations were applied to optimize air and coolant distribution. The design maintains compatibility with the original engine cover.

Frequently Asked Questions
Can the original engine cover be retained?
Yes, the charge cooler intake manifold is designed to remain compatible with the original engine cover.
Is the system prepared for supplementary fuel injection?
Yes, the exhaust section of the manifold is prepared for an optional fuel rail for additional port fuel injection. Injector shut-off plugs are included when this feature is not used.
Are there connections available for methanol or nitrous oxide injection?
Yes, every cylinder runner features its own 1/8" NPT connection for methanol or nitrous oxide injection. Sealing plugs are included.
Is a thermal insulation spacer included?
Yes, a thermal insulation spacer and 12 FKM silicone O-rings are included to limit heat transfer from the cylinder head to the aluminium manifold.
