Are Iridium plugs worth investing in on BMW E46? I've used them on all my other cars and have worked the best compared to Platinums.

I put NGK Iridiums in mine and can't tell the difference

No change in mileage, no change in butt dyno.

Yep - if you can tell a difference, then you waited too long to change the spark plugs

I used Bosch +4 and got a misfire on 2 plugs after 300 miles. Bosch gave me a refund of the purchase price for the set. They are a first class company. It is possibile I may have gotten a bad batch. I went with NGK oem thereafter.

Ngk. Bosch. Compare them side by side. Bosch looks inferior. Bosch is in there now after replacing factory NGK's but next time it's NGK.

So I guess there is no advantage to Iridium vs Platinum plugs? I've gone 60-80k miles w/o replacements on Iridiums either from Greddy/Denso or NGK. Very clean and even burns also.

Expensive plugs do make a difference compared to el cheapo plugs from wal-mart of your fred-meyers special. Performance plugs won't yield more hp, but your motor will run smoother, you will have better throttle response, and better fuel economy.

That is what they'd have you believe.

NGK Iridium IX if available but NGK whatever as they are factory OEM plugs. BMW use NGK for a very good reason, they are the best.
