Recently replaced the long block assembly on a 2005 Mazda3s Hatchback - this being the 2.3 liter non-turbo. carried over all electronics, ...includings plugs :xUnknowingly cracked spark plug # 4 during the motor swap, causing the car to only run on 3 cylinders.Replaced the plugs with cheap-o BOSCH platinums at $2 and change. And when the sales-teenager girl (at a competing parts store... let's call them [@]) stated that they were pre-gapped (according to her trusty computer), I threw them in the car without even checking.The cylinder misfire in #4 was gone, but now I was getting random misfires... causing excess fuel to blow up in my catalytic converter.. my precious, expensive, need-to-pass-emissions catalytic converter.Did a little research, and well, here's the dillie: Mazda uses IRIDIUM spark plugs from the factory. Nothing else. Mazda also uses NGK SPARK PLUGS from the factory. Nothing else. Mazda specified the SPARK PLUG GAP @ .050. Nothing else.****(This only applies to 2005 - 2009 Mazda3s 2.3L motors. The 2004 Mazda3 2.3L had a different ignition setup).****Anyways, I went out, bought these plugs along with a SPARK PLUG GAP TOOL, RE-GAPPED (they were all at .030, made them .050) and installed these plugs. The car started up immediately. During the delightful 106,990 miles I drove the car before oil-starvation lead to a quite unpleasant rod-knock, the car never started this good.And here's to Advanced Auto Parts being the only place that had these plugs. On a Sunday.Thank you Advanced Auto Parts.Lesson learned: Always check your oil so you don't have to go through what I just did.

Comments about NGK Iridium IX Spark Plug:
Changed my hard starting 280z to quick starting.
Big improvement in smoothing the idle too.
Fuel economy seems to be better but I have only ran through one tank of gas since installation of the plugs. I have never seen such a drastic improvement before I installed these plugs.
I recommend these plugs for historic Datsuns.

Comments about NGK Iridium IX Spark Plug:
Be careful. This is a single electrode one. Only after uninstalled my old ones I realized what I need are double electrode ones. If you car uses a waste spark ignition, you'd better go with the double electrode ones. But I'm too lazy to return them back and get new ones. So I just installed them on...
