It's taken a lot of time and money, but the Evolution of Speed N5x intake manifold is finally done, tested, and now available for sale here on our site.
People have asked if plenum volume was increased. Absolutely. Runner dimensions were changed as well per expert advice. Anyone saying that this is just a copy of the stock manifold doesn't have much credibility. It wasn't easy to make these changes work within the factories packaging constraints, but we've done it.
Retail price for the base intake manifold kit (comes with fuel rail and injector plugs) is $1449.95, and the price for the intake manifold kit with fuel rail, injectors, and fuel line connections is $1899.95.
