[supercharged680]

hey guys my car is close to 31k miles now.. i saw the rpm drop to 500 when i was at idle the other night

when do u guys change ur spark plugs? and what have u used for non boosted apps.

think most people stay with stock plugs but at 31k i highly doubt they would need to be changed

Change em whenever you feel you want to. They are not that expensive to replace so at 30-50k I would be looking to change them if it were me. My father has 90k on his stock f150 plugs which yes is stupid, but it still runs fine.

OEM Maintenance Schedule for normal driving calls for 100k out of the plats. Pull them out and see how they look
On cars customers own not leases I change them based on how they look

They are factory Iridium. They will still look almost new at 100K...

Yup pretty much. As long as you keep up on your maitnece and run a decent gas theyll last till 100k (Most of our customers go 8-12k on a regular oil change and burn regular gas and dont go above 40 mph. Flooring there car is a task for them. Should see some of the shit I pull out.
