CL500 spark plugs - where and what?


Well the stealership reckons I need 16 sparks and has quoted me for CHAMPION part number KC11PYP - £104+VAT
Now I may be wrong but I thought CHAMPION were cheap plugs?!?! Id prefer Bosch or something really - esp at £104 + VAT.
Ive found it hard to get definate details on what plugs I can use but I have the list below so far:
Champion KC11PYP
NGK PFR5G-11
Bosch F8DPER
Cheapest for Bosch was GSFcarparts.com @ £84 all in.
Do you guys know of any other sparks? and where to get them at good prices online in the UK?
If you know any good websites + good sparks that fit CL500 2000 V8 then please bombard me with details.
On another note - MB said the engine oil is 5W 40 Shell Helix - wanted a bloody fortune for it - went to shell petrol station and got 10litres for £72 + a free Top Gear magazine :0 - thought that was good until I saw 20 litres on eBay for £80!! just dont know if I'd trust buying off eBay though

Regarding cheap plugs, I think all or most manufacturers sell plugs for under $2 for non platinum and then much higher for their premium plugs.

Thanks for that Jud - only problem is there in the US - I need similar sites in UK - esp as the part numbers for your sparks are different in the UK.


I can get Bosch from Halfords for £80. I might go with them.

yeah price wise I guess I have to bite the bullet and just pay up - I just wasnt aware that MB would use Champion sparks being that they are not as good as bosch. Yeah £80 is about $160 so yeah $10 each.

If so then I dont need to do them cause I only have 55.000 miles on my car

Can someone confirm either way please?
After questioning them a store employee came up to me and said with that type of vehicle it is probably best to use the dealer plugs so I do not hurt anything in engine.
Have any of you ever run into this? Or are you using after market plugs and if so what types?

Hey dude - I would agree that 'dealer' plugs are best but guess what - when I went to my dealer he showed me the plugs and they were bloody CHAMPION KC11PYP - all boxed as mercedes! work that out. And I always thought Champion wernt the best of sparks out there.
I personally want the Bosch ones - although ik now not sure its worth changing them yet as I have no issues and only 55K miles on the car - and apparently sparks dont need changing till 100K miles.
Still waiting for a DEFO on that though.................

Well the best ive got so far is £78 online for 16 Champion KC11PYP - which is what the stealership was gonna sell me anyway for £120!! nice


Hi dude - that was www.spark-plugs.co.uk - however Ive just realised theyve quoted on 8 plugs!! They say we only need 8 plugs. Yet im sure the dealership said 16 - 2 per cylinder. If thats true then it would be £140 - well too high.
SOOOO - anybody out there - can you confirm whether we need 8 or 16 plugs for our CL500 V8's ?



will do it myself also.
