Owner reviews for spark plug

Hij heeft er laatst een paar nieuwe bougies in gezet en nieuwe banden voor apk.

I would also like to leave a comment here about having success with an autolite AR52 plug. Same exact thread size and identical reach as the OEM torch plug.

I have always had luck with the NGK iridium plugs.

Bosch W6DPO. They’ve always been expensive, but now stupidly so. I’m not paying $250 for plugs, either. The DENSO IW20TT you referenced is a perfect replacement because it’s the exact same heat range as the W6DPO.

I just did mine maybe 3 weeks ago from Essab with plugs for like 360. They worked great.

Denso and NGK have fared better than Autolite in my vehicles in my experience.

I owned my cruze for 5 yrs and had no problems with the NGK iridium. I paired it with a coil pack I ripped out another cruze.

Here’s a link that may be of help. Your plugs are quite fouled and even at end of life plugs should not look like that.

I personally refuse to put anything Bosch made in my cars. All were genuine Bosch parts from my local parts place that has never done me wrong.

First it was their wipers, paid good money for them, squeeled worse than the worn old ones. Figured it's a fluke.

Then I had a set of spark plugs, they were gapped correctly, but the car ran like absolute garbage and I couldn't figure it out until I put the probably 20 year old Valeos back in and it ran fine again.

Then I had a crankshaft sensor that was bad out of the box, and that was the last straw for me. I don't care if it's coincidence or a bad batch, or if they've improved it since, I'm done with any Bosch parts unless it's NOS from the early 2000s or earlier.

If you used auto lite spark plugs that is almost certain the problem.
