I had drama's with them on the xh, thought i had them all on right. Idled half decent go for a drive, definatly not right.....sat there for hours f**k around to find out which one wasnt on right or which 2 where around the wrong way lol.

This time around ill do my full service minus plugs and get the pro's to do them

bout a 15 minute job with the car on ground, easy job to do. do it all time at work.

pull airbox and intake hose out, get a bit of strong steel rod with hook (i use a shock absorber packing rod cut down) on end. pull old leads up and off then run new leads with one arm getting lead close to terminal and use rod to position and push on. then get 1/2inch extension bar and push down on each lead making sure to hear a click

as for which terminal is which:
<<front 1 2 3
<<front 4 5 6

Pretty easy job

i will do 1 at a time is it worth chnging the other leads
are there any other leads? eg coil to dissy? im not to sure how coil packs work on ef

nah there is a connector but no need to touch that just 6 leads
