Cayenne S - Spark Plug change

[mail2neil]

Hi Guys

I have a LPG conversion on my 4.5 Cayeene S.

That means I need to change the sparks more often, and they are due now.

Porsche charge £300 a pop to change the sparks. :o

Can anyone recommend a garage near Marlow, Bucks that would do it a lot cheaper, and/or - does anyone out there have a 'how to' guide so I can do it myself?

Many Thanks in advance

Neil

Hi,

Does anyone know what size is the triple square bolt for the stabilizer bar attached to the passenger side of the engine? I want to buy a triple square bit for it.

I think it is M10. same as seat bolt (for battery change).

I used Denso Iridium stock gap, not Beru ($$$). No problems 6 months since I changed it; changed coil also.

When I changed coil as preventative measure, all 8 had hairline cracks.

Lastly removing the silver plastic cover on passenger side is challenging. Be patient or you'll scratch the (plastic) cover.

I wonder why these coils tend to crack like that,,, recently had 40k miles maintenance service and dealer found 2-3 of coils had a hairline cracks on them, replaced under warranty. I've owned numerous brand cars and never had a problem with crack coils...

I've heard you can prevent the silver plastic cover getting scratched by laying down the towel while removing 'em.

not that hard, but you may need a deep Torx socket to loosen the torque arm to get the passenger side plugs out
