C32 SPARK PLUGS & WIRES.....Worth Upgrading???
Hey,
I'm not sure when my spark plugs were changed last.
My car is standard apart from k&n elements (for now)
I've seen magnecor 7 or 8mm wires on eBay are these worth getting?
Also there are loads of spark plugs to choose from but which ones do these cars like the best? Denso iridiums?
Or should I just get new plugs n wires from Mercedes?
Cheers

How many miles have you got? I ordered NGK standard iridiums from needswings and have magnecors to try. There is a long thread about plugs and wires on the forum.

Plugs and wires wear and degrade performance. In all cases new ones should improve the lost performance.

I'm not saying plugs and wires can't upgrade performance but I think that AMG almost maxed out the potential in our cars regarding the ignition aspect. 165k miles and not a noticeable difference in performance is what I was meaning... wires can probably use a upgrade but its negligible.

I went with NGK IX Iridium. They are rating for 100k miles just as the stock NGK plugs. Also 8.5 Mags for the wires. Noticed a HUGE difference but who knows maybe it's because I did 185MM and Stage 2 EC tune at same time, LOL...

Recently got Behr leads and NGK laser plugs, the car is smoother than before (perhaps it a placebo effect). No other performance difference that I can tell. Wheels still spin...gives me a grin...

I upgraded pulgs and wires at 100k miles. I think I was developing an issue with my oem plugs and wires, but once I installed new ones, everything felt smooth. Not sure if I saw a performance difference, but everything seemed smooth again.
