its time to change the pluges in my 01 s60 2.4t wanting to know if anyone has tryed the E3 plugs.

 

I have not tried them in my 850, but I think I'm going to try them out.

I've only had the guts to try them out in one-cylinder engines, like my 33cc 2-stroke & 4-stroke bicycle engines... and a lawn mower. The gain was noticeable but was night and day with the 2-stroke motorized bicycle.

I like the 3-prong look of the Volvo plugs that are in my engine right now. But the E3 plugs have a 3-prong "diamond". The benefits of the diamond shape can be seen here --->
Two things I'm worried about with the E3 plugs are:

(1) They are nickel coated. I don't know if they would really last as long as platinums or iridiums.
(2) They cannot be gapped (perhaps the diamond shape makes gapping a non-issue?).

The price between the E3 plugs and the Volvo plugs are virtually the exact same. So I think I'm gonna try them out since I've experienced short-term gains with smaller, 1-cylinder motors.

And here are the short-term gains verified --->
Just not positive if they'll last as long as they claim they will, and if the inability to be gapped is a real problem or not. Mostly concerned with the first issue.
