best spark plugs for a 202 c280?

[fromthelbc]

hey guys, im going to do a tune up soon, and im wondering what the best performing spark plug that i can get is...? price isnt really a problem because spark plugs tend to be kinda cheap...

[jnenad16]

the best performance is going to be from either copper or silver spark plugs.

their should be a sticker on right hans side under bonnet near rad telling you whar you can use

their should be three types
champion C11YCC ,
BERU 14F-BDU4 ,
BOSCH F8DC4

THIS IS WHAT MY C36 CAN TAKE and the c36 is a tuned c280 and re-bored c280 same engine m104

I always, always, always only use OEM plugs. The Bosch F8DC4. My engine hates when I try anything else.

im the same i hate guys buying cheap plugs and wanting me to fit them

[jnenad16]

I know for a fact that M104 performs exceptionally with silver plugs, however, those are extremely hard to find these days, and they dont last very long either, about 20-30k miles at most.
Nology used to sell them, also Beru had a line called Silverstone.

I have ngk iridiums in my c280 m104. works great, had bosch platinum+4 in there before, couldn't tell the difference

I also use NGK Iridiums. I like em. Kinda wish I had pulled the injectors for a cleaning and flow test at the same time though...

Ive found my M104 C280 only like the F8dc4's from the dealer. LOL

[horgantrevor]

bosch only are the best for fueling and they last last a long time you get your moneys worth

I run NGK Iridiums as well. Cannot tell any performance difference over stock.
