Spark plug Bosch or NGK

August 28 2024 : Spark plug change Bosch 70,588

There is a meteor 350 in my riding group with an iridium plug which i will say he Acquired Unexpectedly, and damn the results are just awesome.

I run more or less the same motor (2.1liter-276 Schrick-10.5CR), and I'm using stock Bosch spark plugs.

Mine had NGK, so that is what I put back in.

I have been using the ngk ruthenium sparkplugs and they work just fine, cheaper than the iridium's.

So I’m running an 03’ with the 2.4 and I put in NGK Laser Iridium but Denso is perfectly fine. I’m surprised how much your plugs cost if your paying list price. The cost price is how much I paid for mine at the parts store. Both plugs are fine to use.

95K, swapped for NGK laser iridium’s (OEM replacement) plugs and since then have had rough idle but when driving feels fine.

Also check the spark plugs, sometimes people are cheap and buy autolites instead of NGK. Cheap plugs from previous owner give me a headache.

Those spark plugs don't look like the highest quality parts. Get some from NGK or Bosch. Better made parts that are more suited to modern engines

The only things it’s done to me is die (dead battery) and a misfire that cause it to go into limp mode at 118k miles (I went cheap on spark plugs instead of doing NGK’s)
