Looking for spark plugs

I’m looking for replacement spark plugs for my Saab 9-5 2.3t my mechanic said I needed ngk pfr6h-10 plugs and that iridium is the best but I’m not sure what sites are reliable I’ve found sets of four on subimods and ZZ performance almost everyone else sells platinum/copper and the companies I know only sell the plugs in sets of 1 or 6 so if those companies are trustworthy or someone knows a good place to get them that would be very helpful

Good advice. The whole story is that Saab used ION sensing which can measure the results of combustion per cylinder after they spark. The spark plug is the tool that measures (to put it simply). So those in the know just use what the engineering team determined so we ensure that ion sensing works correctly. Any benefit from a “performance plug” would be negated by making that ion sensing not work correctly.

Exactly these. Leave them at 1.1mm if standard tune, gap down to 0.9mm if running higher power outputs - but always check with your tuner for their recommendation.

Denso IQ22. They run hell of a lot better than anything else for the 9-5

From looking into it, it seems to boil down to if your Saab is stock or tuned?

If stock, use copper. If tuned, ask the person/company who tuned it on their preference.

NGK coppers. Only choice. Your mechanic is trying to up charge you.

Always get copper plugs, but ngks with the right heat rating is what you want
