Possible To Adjust Gap On Ngk Iridiums Ifr6T11

[mista_khan]

Hi

got brand new 6 plugs for my is200, ngk ifr6t11 , problem is as my cars on lpg my lpg specialist told me to change plugs and re gap them around 0.66ml or say 0.7ml as it makes the gas run smoother ,

question is how can I adjust these plugs without damaging them :(

im a noob like lol

you need to be carefully that you don't try and level against the tip when trying to open or close the gap otherwise you can damage it. Ideally you need to bend the outer electrode on the vertical section rather than the horizontal.

Here is an NGK video:

Standard feeler gauges and thin nosed pliers work, you don't need one of the special tools shown.
