Replaced my NGK BPR7ES with the Bosch plugs today and knocking is gone completely
(at least with 98octane)
Damn thats a good tip.
Measured gaps and discovered that the NGK plugs were at 0,75-0,8mm while the Bosch are all at 0,7mm.
Is that part of the problem?
The old plugs look alright?!
how mka your head with bigger valve? expansive?
