Hello,

I was going to replace my spark plugs on my 97 SL500 I recently got, but I didn't know how many spark plugs I needed?

Also, what plugs should I get? I could do Bosch copper, but I'm partial to NGK. However, ngk.com told me to get BK5RES, which is a resistor plug. Anyone know what is the right NGK plug for my car?

Thanks!

You need 8 spark plugs..........Go with Bosch.........NGK don't work good with Germany car.......

I was going to get both Bosch & NGK's. I thought I might try the NGK's and see if I have any trouble with them. But they'd have to be the non-resistor type. My thinking is that NGK's ceremic is reputed to be more pure and so less prone to detonation.... I could be wrong.... :p
