NGK advanced V-groove center electrode provides optimum performance and fuel efficiency required by today's lean-burning engines. NGK V-Power Spark Plugs also are ideally suited for race cars and high performance street cars. Today's performance engines are high compression/high stress applications. Many are supercharged, turbo-charged or nitrous oxide fed.

Sean's Notes: These plugs are a step colder than the standard plugs and are an excellent choice for forced induction projects in your NA or NB. These plugs come gapped at .044, please take care to gap your plugs properly before installing them!

REVIEWS

After reading many other positive reviews on both the GWR and Miata forums I finally decided to buy this product. My main concern for many months was whether or not I was up to the task of installing the header. But with the excellent instructions on Brian's forum as well as several Miata forum threads it turned out easier than I expected. After receiving notice that the header would arrive on a Friday afternoon, I began the disassembly process. After about 3 hours I had the stock manifold out. Later that afternoon the new catted header arrived right on schedule. And it is a thing of beauty. I opted for the stainless version. Installation on Saturday morning took another 3 hours, although I could have shaved some time off of that but I was actually enjoying the process of double checking torque values and cleaning up my engine compartment. I already have the GWR catted midpipe, so that connection was a snap. I put everything back together, reconnected my battery, and went for a drive. NO CODES! Nice throaty sound with my RSII muffler, and a significant boost in power and low/mid torque. Another happy camper here. I since have added a M-E tune and I feel I have realized all of the gains that Brian has achieved on his 2012 project Miata. I've put several hundred miles on my Miata since the install with zero problems. This is the car that Mazda should have built all along. Thanks Brian.
