Forgive me if it's been posted before but is the Denso 3381 an exact replacement for the LFR6A? Being told it is but the cross reference is saying it's also good for the LFR6A-11.
The plug th reference may cross to both. The difference is the gaps. And from what I have read, gapping the -11 down to what our engine spec is can possibly cause an issue/failure. Other than that I believe the plugs are the same.
