My engine is stock I have exhaust thats it. I will be turboing my car most likely in october-novemberish. I could use a tune up right now (plugs, wires) My question is, is there a plug that will work for my na engine now and also work GOOD for my turbo set up later? And I plan on going with a new set of the stock NGK wires.

 

Well, you didn't tell us which engine you have, but if you're running Bkr5s, go ahead and get 6s, and gap them to about .025" when you do boost it. If you plan on running a lot of boost, then look into 7s, but don't expect them to be in stock.

 

Oh sorry its the 1.6 and I'm fairly new to miatas so what brand are those that you posted?

 

NGK

The 6s are the default 1.6 plug in most parts store computers.

 

Cool thanks

 

NGK BKR7E or BKR7E-11 will be in stock at NAPA, and probably at lesser parts stores as well. This plug is one step cooler than the factory spec for the '90-'93, and is pretty much the defacto standard plug for moderately boosted Miatae. Gap them to .025" for a stock ignition system, .040" for a COP system.
