What Spark Plugs For My Pinto 2.1L ?

[Guest david_l_perry]

Got myself a little confused yet again.....takes very little....

 

I am about to do an oil/filter/spark plug service on the Hood and took the plugs out to check what they are so I can get the same type.

 

They are noted as NGK AP6F.....

 

Figured that was fine....but now I find bloody loads of variations on that type....

 

Am I missing something or should there be another reference on the plug ??

The AP6 are fine in fact unless you are running seriouse compression and a wild cam any standard plug for a Sierra will do

The engine has a 285 piper cam fitted, obviously its been working fine with these plugs fitted from the short time i have had it. Its simply a case of what plug i get as I cant see any plugs that dont have an extra letter noted....

 

Another novice question is what gap should the plugs be set at ? As the engine has been changed from stock i dont know what to reference it against....

According to the NGK web site for a 2.0l sierra OHC

 

Part No APR6F-VG4

Gap 0.6mm

Std plugs will be fine unless it's race tune++ mowerman

sounds okay dave, but the plugs fitted have been in 2 yrs and max 2000 miles, good clean and regap should be fine,

 

when servicing grease the uj's on propshaft too, *bleep* to get to front one but needed all the same,
