Dears,
I have big confusion with spark plugs for my engine 5.7L carb number OC602940.
Recently replaced with another long block (inl. heads), I was troubleshooting some problems with it and I decided to replace the spark plugs, I went to a shop and they missed the NGK BR6FS I had on it.
I took my phone and made a quick search for mercruiser 5.7 and found out this code: NGK BPR6EFS so I bought 8 of this.
I was surprised when I saw how different those BPR6EFS were by the BR6FS... BPR6EFS the long reach plug how can they be both ok for the same engine ? Am I going to make big damages to my motor if I use the BPR6EFS ?
Thank you !
