I'm want to increase hp on my XJS 5.3L. I have a few parts in mind I would like to replace that may add extra power. I bought a new distributor cap, gasket, rotor arm, spark plugs, dist. air filter, fuel filter, and oil filter. Does any one know where I can buy a lead kit, PCV valve, and oxygen sensor? I'm having a bit of trouble finding them...

George,

Thank you. I found the lead kit on SNG Barratt and the oxygen sensor on Coventry West, both reasonably priced. Still no luck with the pcv valve. Would you know if I can order this part through a Jaguar Dealer?
