I'm changing plugs putting in iridium types are the gaps set at factory? If not is it 0.05? Thanks

    They are usually pre measured before leaving the factory, however due the shipment of the product it’s a possibly they have been pumped around and have bent them out of shape.

     

    as for the gap I believe they very, best bet would to check the owners manual to see what they recommend the gap size to be.

    Hi Tom, if I remember correctly the recommended gap was 1.3mm but read somewere, may be on here, to reduce it to 1.1 - 1.2mm to reduce the load on the coil.

    Yes 1.2mm is about right, I initially read the first post as 0.05mm, not inches lol!
