How to: Remove the spark plugs

[interloper393]

i usually just wire brush each one, just keep turning the plugs to get at it from every angle

In the diagram picture above, labelled 1-4... which ones are leading plugs and which ones trailing?

Also... NGK BUR9EQP and NGK BUR7EQP... I have two of each. Which are meant for leading and which for trailing?

Also have a set of Magnecor leads to fit also. Are these easy to do as well?

Thanks for the guide. Great help so far!

Is it wise to copper grease the new plugs too when putting them in?

[interloper393]

1 and 3 are the leading plugs bud, you`ll know when you see them as they have 2 blue bands on the white part of the plugs.
To fit the leads you need to remove the oil filler neck, a few 10mm bolts i think from memory :S

Hope this helps

Not sure on the copper grease tho lol

[Tiger_kpt]

I\'m guessing that NGK BUR9EQP are the leading type?
And NGK BUR7EQP is the trailing type?

I\'ll have a go at doing the plugs and leads tomorrow.
Can anyone point out the AST on a picture? As have a Pettit Racing one to fit.

Yeah I always copper grease plugs slightly when putting them in to stop them seizing. Well I always have done on piston type engines. Wondered if it was the same with Rotary.

[interloper393]

cant see it doing any hard man, just a very light smear maybe?

The yellow cap to the right is the ast bud.

[Tiger_kpt]

Sweet. I\'ll get that fitted tomorrow too then. Do you know if the AST hold water when the engine is cold? As in... when I remove it to fit the new one... will it **** everywhere? lol.

Want to try to do this stuff myself so that I can save a bit of bread when it comes to going to WGT\'s it a week or so for a load of work.

[interloper393]

not 2 sure.. just bung up the pipes you remove the top up if needed? never fitted one dude so aint got a clue lol.. make sure the cap fits right tho else you`ll loose water..

I\'ve always found NGK plugs to be a bit poor. I know most use them on here with no probs but they made my scoob run sick as a parrot.

I used HKS Iridium plugs in my Type RS and they were superb. Also in the STI.

HKS plugs are made by NGK

7s are leading. Colder plugs generally for trailing, but 9s all round are a cheaper alternative that most use on here (mild tune).

The ast will have water in it, so just bung up the hoses or be quick and plug them onto the new ast as soon as you remove from the old.

I changed the spark plugs on my FD and did all 4 of them from underneath the car, took 10 minutes and did not need to disconnect anything. Just jacked up the passenger side, axle stand underneath and there job done. Tools used was the plug socket and a 2" extension bar.

I ordered them from Pettit Racing in the USA. Ordered quite alot of parts from them, Cracking service and good price.

This time next week i\'ll have the REX back with a load of different goodies fitted. Canny wait!
