Can anybody please advise me about the best way to replace the spark plug leads on my 1/96 Futura six cylinder. There must be some alternative to removing inlet manifold. I am thinking maybe from underneath???? Any help will be greatfully accepted. Thank's

No need to remove Inl manifold. Just remove the airbox assembly, so its not there, then you can reach in under the manifold. Just mark all your leads (number them, biro works) that are close to the lengths of the old ones, thats if your using non-genuine parts.
Hope this helps.

Thank's cjh, I will go and try that now!!
