Spark plug gap for ST170 (Denso Iridium)
 

Hey all,

Stupid little question, but I can't find an answer anywhere on Google for this -- does anyone know the correct gap for Denso Iridium plugs in an ST170?

If anyone has any experience with the aftermarket coil packs too, do let me know ... (as I'm planning to do coil/HTs/plugs as a batch this weekend)

Cheers all,
Dan

0.8 mm for plugs and I changed my coil pack over to cfm msd coil pack and leads from pumaspeed about £200

have the same msd ignition with magnecor leads and I set mine at 1mm some say 1.3 but that causes flat spots and the tuner I used also told me 1mm is good to go so agree with above
