its all a load of nonsence with aftermarket plugs and leads. Vauxhall only use Bosch twin electrode type and these do the job just fine. You wont get better than GM/AC Delco silicone leads either.

jsut buy the original plugs & leads from vauxhall

dont listen to crap about super plugs & leads etc

think they come with bosch plugs ,but ive been told GM ones are some of the best

vauxhall ones are good because they are designed for the engines, i prefer ngk personally,dont go for bosch super 4s my 1.6 16v ran crap on them and splitfire plugs are all a gimmick

can u buy after market ones that are better than vaux for the corsa c?? wat would be improved?

k

no you won't fcuk anything the spark plugs are under there.disconnect the plug on the right and take out the bolt's and this will pull out

Everyone keeps telling me I should check my plugs for the reason my cars been feeling slow lately...

I removed the plastic cover on the top of my rocker cover and there was another plastic thing on top held down by 2 bolts with star shaped alan key style things to get them off... it looks like there's a load of electrics going down this or something?

Whats underneathe if I take it off? will I fuck anything up?
