Ultra Street Intake Manifold for Mazda MX-5 Miata (NA/NB) 1.8L by Skunk2

Building upon the performance legacy of our Pro Series Intake Manifold, as well as using the latest in CFD (Computational Fluid Dynamics) software; Skunk2 Racing has created a three-piece modular design that allows for easy disassembly, porting, and plenum volume changes through the use of a removable plenum. In addition to CFD testing, the Ultra Street Intake Manifold has undergone extensive in-house dyno and on-car testing which has led to a design that is less restrictive, yielding both torque and power gains well over any other offering!

Skunk2 Racing Ultra Street Intake Manifolds are cast-aluminum, manufactured from high-grade 356 aluminum alloy for strength and lightweight. Each manifold is CNC-machined for a precise fit, and individually inspected for quality assurance. The Ultra Series Street manifold features a generous 68mm throttle body opening and is constructed with thick walls at entry, minimizing concerns of breakthrough when port matching. Intense planning and design went into the plenum (1.8L plenum volume) to distribute even airflow to all four cylinders under dynamic load conditions. Placement and design of the velocity stacks were rigorously flow tested to ensure maximum delivery of air to the cylinder. Large velocity stack raised bell mouth entries lead to 10.00” long intake runners with smooth transitions allowing the Ultra Street Intake Manifold to outflow all other production intake manifolds.

Fits well

Fitment was good very different from stock they should advertise you delete almost everything (air valve, EGR , almost all of your vacume lines) the intake gasket that comes with it is not the greatest quality would use oem. Fitment is low witch makes lower bolts a pain to get in need S wrenches to get them. Sits lower for my na so sits touches fuel lines had to bend and reroute. Comes in contact with charcoal cansiter you'll need to delete that as well. Throttle cable bracket flemsy buy aftermarket one 97 fuel rail didn't fit might have been because of 99 head but fits perfect with radium fuel rail finish was good could send more fittings for vaccum lines
