Hi all

Right story so far cap, arm ,coil and leads all arrived ok apart from the spark plugs as i was going to try some fancy multi earth point plugs. now question for you. would anyone be able recommend a performance plug and if so what was the part number if you can remember, and where you got them from.

I want to try a performance plug rather than standard as I thought I would try some performance leads. So want a good plug to go with it . as I use the car on track sometimes too.

Thanks

Dont waste your money on performance plugs on this engine the ignition system is to old hat and it wont notice any improvment and neither will you,want the best? fit NGK want less then play with Bosch,Splitfire,Champion etc,you can use BP7ES NGK also cheaper and do the same job,never quite sure why TVR fitted B7ECS plugs to be honest,but either type work just dandy its the correct heat range thats more important rather than the electrode style.

All plugs do is ignite the mixture, nothing more, and the stock plugs are quite capable of doing this on an engine running around only 60 bhp per ltr. You only need trick leads and plugs for very high compressions, or alternative fuels that are harder to ignite. You will gain nothing extra on this engine, so save your pennies.
