The difference with other spark plugs was large enough for fellow passengers to notice it, both in comparison with the same mark and type of car but 10 years younger, and with the condition of my car before the change. Especially in the humid climate here and for elderly cars, these spark plugs are in the class of "must have".

Installed these to my Subaru Legacy 2.0 AWD. Works very well and car seemed to accerlate better with these than old spark plugs that had 30 000 kilometers behind them. I have now drived 500 km with these spark plugs without any issues. Too early to say how lobg they last but they work well at the moment.

I've used Iridium plugs in both my auto's. Actually feel seat of the pants response from them in both cars. Seem to add a crispness to the low end of the engine performance... Though the mid range and top end RPM is a little wraspier as well...

I used them for my Hyundai Accent 1.5 12V 1996. It works great. I haven't any problems with these spark plugs yet. They work fine even in high RPMs. 10/10

I ordered these for my 07 Volvo C70, but they are wrong for this car. Some other supplier said they would fit, but don't. They will fit a few of my other Volvos, so that's where they will go. Good plugs at a good price.
