spark plugs

[house]

hey guys, I've been reading a few forums on faulty spark plugs causing bad fuel economy, my jk has done just over 50000 km now and I haven't changed my spark plugs since new.
has anyone ever experienced an increase in there performance and economy since changing over there spark plugs and leads ???

cheers

Yes. I replaced my plugs at the 48k service like recommended and found one was cracked. Also found a dodgey lead so replaced them too. No more rough idle or missing occasionally. Got the plugs from the US fir about $7 each instead of the $20+ asked for locally. Leads I needed in a hurry so got them from Melbourne but if not un a hurry I would recommend US for them too.

And did you find that it improved your fuel economy mate ??

I think you will find a slight improvement if it was running rough before hand and needed to be replaced

$4.50 at auto one store in WA. Why not change them every 24k for this price?

For replacement leads contact ICE Ignition in Melbourne, better quality than anywhere else and cheaper than genuine, he copied mine so now has a list on the lengths for JK
