Whats the procedure for changing the plugs on a Jaguar sovereign?

Any special tools required and what is the gap setting on the plug. Jaguar is a 4.0L Straight six cylinder.


Thanks in advance|||No special tools - just standard plug socket. As mentioned do them one at a time.





Gap is pre-set on the plugs and should NOT be changed - and I would recommend you ONLY buy the manufacturers specified plugs as Jaguars can be a bit temperamental if 'cheap' plugs are used.





(Had 2 XJ8's and a 4.0 S-type)|||Just like any other car.A ratchet,plug socket and the parts store can give you the gap.Take one plug or two out at a time so you dont mess the firing order up put the new plug in tighten it put plug wire back on and repeat.|||You can check this site and see if they have any tips on that car.
