Having the B350 tuned. so many spark plugs and ignition wire brands to choose from.

Any recommendations?

A friend recommend these. Any thoughts?

Stay away from the rare-earth plugs. These engines don't like 'em. Standard copper, from the manufacturer of your choice.

Pick up some 'premium grade' 8mm wires, distributor cap with brass terminals.

 

Excellent -- thanks for the info.

 

I agree with HeyYou about the best performance witrh copper...

I got tired of changing everything out every 5-10k miles...thats as long as the plugs and wires last here in South Florida. So I went with:

More Information for STANDARD MOTOR PRODUCTS 10073 (rockauto.com) --- Ceramic boot spark plug wires
and
More Information for ACDELCO 41806 (rockauto.com)

Yes the plugs are double platinum, and they do idle just a tiny bit off - but I havent changed anything in 20k++ milles and Im still getting the same gas mileage (12-13mpg) and no codes.

 

@ElkCon -- based on HeyYou's comments, I went the easiest route and asked the mechanic to use Mopar parts. Next time around I'll use your ingition wire rcommendation.
