New spark Plug wires

[Dan929CDX]

I have a 96 Merc 225 and I'm thinking of replace the stock wires that have been on it since it was new with http://www.bobsmachine.com/Pro...k.cfm these wire from Bob's Machine shop. I was wondering if it worth the money and if I will see any increase in performance. I would think it would be a small gain if anything. Just looking for some feedback before I spend 40 buck.

Thanks

Those are decent wires.... however, I would not expect ANY notable gain in performance (unless your current wires are faulty or leaking).

One note: RESISTANCE in the secondary ignition on these 3L EFI models is VERY critical. Even slight changes or variances can have adverse affects- and ONLY the Champion QL77CC Spark Plug should be utilized.

The OEM wires are actually a very good quality wire as well.

I am running the NGK plugs in my motor right now, do I need to change them or is the difference minute? I think I read or heard somewhere that on a Carb motor these were better than the champion but I may be wrong. Just so we are on the same page my motor is a 3.0L Carb not EFI.

Thanks again,
Danny

Danny:

This particular question is a PERFECT example of why it's SO CRITICAL to provide your engine serial number.

Even knowing that your engine is a Carb Model.... it's impossible for me to accurately ascertain WHICH spark plug is indeed correct.

Earlier models utilized NGK BPZ8HN-10, while the later (CDM Ignition) models utilized EITHER NGK: BPZ8HN-10 OR Champion QL77CC.
