Bought a set of HKS iridium plugs for my o3 STI mid week and had a spare hour so i thought ill throw them in while its nice.I have changed plugs before on my BMW and dont mind getting my hands dirty but when looking in the general location of said items i just smiled and put my tools back in the box and had a cup of tea instead.Does anybod have an easy way they put there plugs in or do i have to take half the engine out.

Not done the job but knowing where they are - jack up remove under tray and do plugs from below.

Good luck shouldn't be a problem if you have a dcent jack. Also VVVV important don't get under car without using axle stands.

I recall reading somewhere that the best way is to remove the airbox and the washer bottle and it improves access. I'll be able to let you know in a few weeks when I get around to it.

yep dont jack up or go underneath at all, Remove airbox nd washer bottle and a 30min job although fiddly.

Convincing yourself to do it is worse than actually doing it!
Once the airbox and the washer bottle are out it's OK, however, you may need to mix 'n match extensions on the plug socket to get into the deep plug recess.

The easiest way is to get a fella in to do it, thats what I did.....

your right mate thats how i didi mine piece of **** after doin that!

I've done it with a hot engine a few times...burns to proove

Paitence, a good socket set with a UJ, plug socket, and assortment of extension bars is all thats needed. Do from the top of the engine, remove washer bottle and airbox if you have big hands. Can be done with them in situ if you can get a 12yr old to do the job for you

If the car has individual coil packs, do not twist or put bending forces on them when trying to remove them, as it can damage them internally (the core is ceramic insulated; i.e brittle ).

Remove the rubber retaining bung in the plug socket when inserting the new plugs, or you may end up leaving the socket and/or the extension bar inside the cylinder head. Not the end of the world if that happens, but it can be fiddly.

Final note; when buying new plugs. CHECK PRICES. NGK are the best plugs, but they can be had much cheaper than their quoted RRP; a set of 4 should cost no more than £30

Thanks for the help and advice,i went with the removal of washer tank and on the other side took the air box off.The air box side was slightly easyer.The only snag i had was when i dropped a socket and had to take the belly pan off to find it, never mind jobs done,Thanks for the help guys.
Hey by the way have any of you used HKS iridium plugs will there be any improvement be it a small one.
I have been told they dont last very long.

Waste of money to be honest mate. Jap mags impreza ra actually lost 30bhp when they fitted iridiums.

FWIW, you can move the washer bottle without disconnecting hoses (and therefore loosing water).

Just unplug electrical connector from pump and after removing two (iirc) bolts, wiggle washer bottle out and there should be enough play in hoses to sit it on top of suspension strut..

It's actually easier than it first looks..!
