so what kind of spark plugs are u guys and girls running in your 22re i know denso and NGK are the only u should use but what about the hotter plugs from NGK or denso ? are they safe to use?

 

NGk is good but I only run Denso. I get mine from the dealer along with a rotor and cap with what the factory suggest.

 

I agree with Terrys87. I also get my ignition parts from the dealer.

Unless you have a specific reason for going with a different spark plug, I would just stick to the recommended part numbers given in the Owner's Manual.

Denso (Nippondenso): W16EXR-U
NGK: BPR5EY
