Thank you. You have rated this product.

Good-Win Racing is proud to introduce the Skunk2 64mm Pro Series Throttle Body for the Mazda Miata in its exclusive, hard anodized finish. Internal diameter 64mm (external 2.75 inch). The Skunk2 64mm Pro Series Throttle Body is designed to be used with the OEM intake manifold for bolt-on horsepower and torque gains by maximizing engine airflow.

Skunk2 throttle bodies undergo an extensive design and testing process to produce a throttle body that doesn't just provide more flow but retains smooth drivability and OEM throttle characteristics. Each Pro Series Throttle Body is designed using the latest CAE (Computer Aided Engineering) tools, which results in a unit that exceeds industry standards. Pro Series Throttle Bodies are also CNC machined from forged, billet 6061-T6 aluminum and hard anodized for durability in Skunk2 s signature finish. Pro Series Throttle Bodies are also compatible with OEM throttle cables, which simplifies installation. Each Skunk2 Pro Series Throttle body also features sealed bearings for smooth operation and ultra-strong, upgraded shafts for ultimate durability. All necessary hardware and a new throttle body gasket are included for trouble-free installation.

A larger throttle body is key to producing additional power throughout the powerband on modified engines with increased airflow demands. The Skunk2 Pro Series Throttle Body for the Miata features a large 64mm bore, which results in significant horsepower gains throughout the powerband on heavily modified boosted and high RPM naturally aspirated applications.

Dyno Comments posted at Miata.net thread from Tester and CSP class racer Scott Fraser: "So Dyno results are in. (We did not bolt up a stock throttle body that day to back to back test but we have dyno results from every dyno the car has ever had. I did clean up the mating surface of the intake manifold to the throttle body to make it flow better for the larger throttle body (see previous pictures in miata.net thread show what was done.). Below 3200 rpms the engine lost a little hp and tq, from 3500-5000 it had a steeper curve, making more power and tq. At 5000 to rev limiter the car roughly gained 5-6 hp and 5-6 foot pounds of torque. We drove the car last weekend and throttle felt great. Now we need to focus on everything else."

REVIEWS

Brian, Thank you!!! We last spoke in November about some upgrades for my 2011 MX5 soft top. It has finally warmed up in NE Ohio and two relaxed weekends of wrenching on my car were well worth the effort. Installation of the RoadsterSport ceramic coated street header was straight forward and took under 8 hours, including a 40 minute test drive and cleanup of the garage! Combined with the RoadsterSport Q exhaust, the sound is fantastic and the increased torque, horsepower and performance make it a blast to drive. The addition of the Cobalt shock tower brace, Racing Beat sway bars, ILM front power train and X braces really enhanced the ride - minimal body roll, comfortable and very responsive. Your recommendations really helped transform the car from great to fantastic. Your research, product development and candid recommendations make you a standout in the industry. My only questions are - what's next on my list .... And how soon will my wife want the same upgrades on her 2012 PRHT ... Again, thank you!!! Charles G
