to cut it short

 

Jap tt 91 auto, new NGK uk plugs in her (PFR 11C).

 

do i have to gap them myself? OR do you leave them alone?

 

If so what should they be??

 

 

thank you

 

JIM.

dunno what gaps or if they come pre-gapped, but if you check on the online manual then check the gaps you should have the answear.;)

Std gap is 0.044".

 

Use decent gauge!

thanks simon

 

ill give them a check tommorow.

 

is that what they are set at when boxed?

 

 

jim.

You might be lucky and get 1 or 2 out of your set with the right gap, but you'll most likely find that you've got to adjust them yourself!

Cheers, Simon (another one!)

Dunno!

 

Have a set of iridium tipped here but not measure the

gap yet, mainly because I've lost my feeler gauges.

Evening simon, tyhanks for the spark plug tip, the car seems to go much better, and I now have a code 55!!!

 

I had to open them all out to 0.044!

 

 

many thanks
