For literally decades, Racing Beat has recommended NGK Spark Plugs for Street, High Performance, and Race rotary engine applications. The NGK BR9EIX spark plug is recommended for use in non-turbo, street-ported, high performance rotary engines used primarily for highway (sustained moderate RPM) driving.

The installation of this "EIX" series spark plug requires the use of a "Thin-Wall" socket--Racing Beat P/N 11529.

Price shown is for one (1) spark plug.

Specifications: NGK BR9EIX

Note: The use of spark plugs other than the "factory recommended" plugs requires the use of a "thin wall" socket. Installation and removal of these plugs requires the use of the Racing Beat Spark Plug Socket 11529.

RE: RoadsterSport Stainless MX5 Miata Midpipe Part# 60-1328: I love the mid-pipe!! Not only is it beautiful, but it makes the sounds coming out of the 'race single' exhaust even better. The two go well together, and it mellows the decel drone a lot. I'm very happy with my purchase.

I received the Roadstersport II, and I wanted to compliment you guys on an awesome product. The Miata should have these on from the factory. They make a great sound, that is not obnoxious at all. The exhaust also installed seamlessly!!! I will buy all of my Miata stuff from you in the future. Thanks,
