986 S replacing plugs and coils at low cost

[shred]

Just in case anyone's developed a misfire and need to change the plugs and coils on their boxster, or if you just want to change them in the course of routine maintenance of course.

I got the plugs (bosch) and packs (HAAS) on eurocarparts for £120.00 last week (offer weekend) and they were dead easy to fit even with my very limited mechanical skills (youtube) if I can do it anyone can!!...saved a lot of dough

cheers all.

That is good news.
Can you just give us a brief run through of what you had to do to completion of the work.
IE..... How to get to the area where the plugs and coils are.
What is required in tools etc.
Also, are any of the parts microchiped in any way that may mean they may not work.

This could be an interesting topic, as I would be happy to complete this work myself.
Last but not least... Are the parts fitted genuine porsche parts, or copies.
Many thanks.

Gadgit.

Will do these myself soon... Stupid question probably; do I need to do anything with the battery while changing the plugs/ignition coils?

Thanks

I youtubed 'road and race' and I think they suggest taking out the relay in the rear boot but I didn't bother, just make sure no one is messing about in and around your car while working on it.

you will need an extension bar for your plug socket and it really helped to remove the wheel arch liners (two 10mm plastic nuts) impossible to do without liners out really but accessible with a jack and axle stand, nice easy job and saved loads. Just be gentle putting everything back, very little torque needed on any of these bits!,

cheers and have fun!

I used bosch plugs and HAAS coils, judging by the packs that came off it looks like these parts are all made in the same factory...absolutely identical to the Porsche ones, time will tell though I suppose...

I think all this 'genuine' parts stuff is largely bullst.

cheers

The HAAS coils are cheap cheap budget ones, the only ones to fit as OE replacement are the Beru ones, and there are 2 versions of those aswell, depending on model age.

What's the difference please Chris?, they appear to be identical.

Having done this myself, the following are all very useful...

Low-entry jack
Axle stands
Selection of various length extension bars
Torque wrench (you REALLY do not want to strip your cylinder head threads!!)
Squirt of plusgas on the arch liner locating pegs the day before you strip it...if corroded they can shear off easily even though it's plastic nuts

Also, be very careful when initially locating the new plugs (use extension bar and plug socket only, no ratchet, just to get it square) and also make sure there's no misfires before you go putting the wheels back on! It's actually quite easy for the plug leads to look/feel like they are located on the coil packs, but they aren't...

hmmm.. Well, I should order all the parts and leave this to my indy as usual than. sounds a bit too much!

I wouldn't necessarily be put off by that, He's absolutely right to say that the leads need to be properly in place before you're done but they make an audible click when they are seated...can't miss it really...if they haven't clicked they're not really attached, that's all.

Explains fully what to do, plus there are many other useful videos about boxsters as well.

No, it's really not hard with even basic spanner skills. You could ditch the jack, and use the car jack. You really don't want to working on a car without axle stands as you already know. The extension bars are really more for the torque wrench...obvsiously it's much bigger than a ratchet and you need room to move it. Plusgas is a 10 second, night before job.

TBH without sounding patronising if any of that scares you then yes, perhaps do leave it to an indy, but if you can change the plug on a lawn mower and you have a degree of self preservation and common sense, you'll be fine.
