There are 2 sets of AC Delco plug wire sets listed on Rock Auto for my 2002 Blazer.

9746KK - $42.79
746KK - $80.79

What's the main difference(s) other than cost?

Is the difference worth it?


Everyone always says to use OEM parts when it comes to tune ups and ect.

 

746KK is their professional grade and 746KK is their standard replacement. If you look at the quality of the 746kk they are similar to what the factory installed. The quality of the 9746kk quality is similar to what you find at your local auto parts. The extra cost for the 746kk are worth the quality and durability.

 

I just ordered a set of the 9746KK. They should be here on Tuesday so if you would like I can take some photos and post them.

 

I've used the 9746KK before (6 yrs ago) and thinking about new wires again. Just wondering if the extra cost is worth it. Someone also recommended these as well.

Darn, I just posted on another thread about this. But, me has confusion. Delco lists the 9746KK as the professional grade. And 746KK as the OE. So why is it being said here, that the OE is twice the cost?
