Hi All

Seen plenty of guides about for replacing oil but nothing for the plugs. It is quite cheap to pick up the full service kit including plugs/air filter/oil filter etc.

Is there a guide or anyone explain how to do this ? Including the air filter replacement??

I cannot even find a decent guide to accessing the engine. The oil change seems simple enough.

Also what viscosity/brand oil should i put back in. In UK, was thinking 0W/40 mobil1.

Is a 984 04 plate.

Cheers
 
Access to the plugs is from under the car and you need to remove the rear wheels - remember it's a boxer engine so it's a flat configuration and the cylinders are horizontally opposed. You'll need an allen key socket to remove each coil pack to access the plugs - they're very deep set inside the engine block. It's not a difficult job as long as you have some idea what you're doing but I stress be very careful screwing the new plugs back in and don't crossthread them - also be very careful with the coil packs as they are plastic so don't overtighten the allen screws. I did mine on my then 986S (now got a 987S) and it took me about a leisurely 2 hours or so.
 
Cheers mate. How did you support the car ? I know the jacking points are weird and have seen the 'hockey puck' adapters etc.

Also is there a guide to remove roof for access to air filter ??

Removing the roof (actually "putting roof in to Service position") is all covered in the owners handbook - it is in mine anyway.

Takes about 2 or 3 min once you've done it once. [:)]
 
You dont have to remove the rear wheels.???

Just a cheap pair of car ramps provides ample space underneath
The coil pack is on the end of each plug - you cant miss them - they are the black things with two wires going into them - there are three on the right and three on the left of the engine.
These coils are held in with two small allen key bolts - not sure what size they are now as ive not done the plugs for a few years- Anyway - undo these bolts and pull the coil away from the engine - they are a bit stiff but they will pop off - cant remember if you need to diconnect the wires first but seem to think there is enough slack to simply pull off and leave dangling

Then get the spark plug socket on a long extension - i used a 3/8 drive socket set - feed it into the tube where you pulled the coil out from and spin it around in your fingers - this will locate the plug and latch onto it - then fix the ratchet to the extension and rotate anti-clockwise - this will remove the plug

Simply reverse everything to refit the new plug and repeat another 5 times with the other plugs
 
OK so you don't need to remove the rear wheels but it makes access so much easier.

From memory they are Beru spark plugs but I got OPC to price match the quote I got from Halfords.
 
Removing the wheels dont aid access - just lets a bit more light on the job.

Not having a go rowtietowers but your first post saying you need to remove the wheels just produced a percieved problem with the jacking up of the car and then axle stands would be needed before you got underneath - Just thought someone may be a bit peed off if they removed the wheels, jacked it up, placed it on stands, got underneath and discovered they didnt need to do all that
