Mazda Rx7 Break-In spark plugs BUR7EQ & BUR9EQ

We recommend this set of spark plugs for breaking in your rotary engine. When starting your engine for the first time there is a high possibility for the spark plugs to foul out. Also with our experience with single turbo rotary engines these plugs are only good till around 10psi and then it is highly recommend to switch over to a set of the race plugs. 

What is included:

  • 2 x BUR7EQ
  • 2 x BUR9EQ
