This manifold is patterned after the popular JDM Type R manifold with some additional refinements. The plenum chamber has been lengthened to provide additional plenum volume when used with a supercharger, turbo or nitrous applications. Nitrous bosses are located on the underside of the manifold. Available in a highly polished show version as well as a standard satin finish. The Power+Plus Whirlwind manifold also features a 65 mm inlet. This manifold was designed and developed with expertise supplied by the engineers at Advanced Engine Breathing Systems, one of the premier Honda tuners in the U.S. AEBS supplies blocks and cylinder heads for many of the most successful Honda racers in the country. AEBS won the NHRA 2001 Pro Import Championship and also won the NHRA 2002 Pro Import World Finals running their own car. The POWER+PLUS Whirlwind Manifold for Hondas is intended to be the ultimate street performance manifold. Unlike all-out racing manifolds, good bottom end power is retained. Note that the JDM Type R manifold is quite expensive while the Power+Plus, an improved version of the JDM, is much less costly.

This new manifold is similar in design to the Type R model shown above. It also features a larger, longer plenum which provides better distribution to the last port runner avoiding starvation normally found on turbocharged, supercharged or nitrous equipped vehicles. The main inlet is 65mm and can be easily opened for larger throttle bodies if desired. This manifold has had all of the vacuum ports as well as some accessory pads moved to the back of the manifold for a clean, uncluttered look. It also features additional vacuum ports compared to the stock manifold. It is designed as a bolt-on replacement for the stock manifold. This manifold eliminates the two-stage design of the stock unit which eliminates flow restrictions and provides for more top end power. This manifold also has nitrous bosses integrally cast into the runners on the underside of the manifold for those of you who would like to utilize a port injected nitrous system on your engine.
