I have ordered new plug leads and distibutors from Rock Auto on the strength of what I read elsewhere in the forum. The plugs themselves? Well I bought them from Halfords as they were the ones they specified for the car . They are Bosch, copper cored I think. It looks like they aren't the right ones. Can you tell me which are the right ones for this model and the gap. When I fit the leads and dists I can fit the correct plugs. Thanks for your swift reply, look forward to learning loads about my lovely Lexus. Paul
