Which are better plugs the AC delco platinums or the AC delco rapid fires the rapidfires are 4.99 and platinums are 6.99 but the rapid fires are a platinum and they say performance plug just wondering which would be better being that they are both AC delco platinums

 

stay with the reg ac delco plugs, dont bother with the rapids...

 

Feel free to try whatever you think is worth it. It's your money. But when you get a stutter/hesitation in a little while, just know we're going to say go back to regular delcos..

 

GMspec'd the Double Platinums for the engine, so stick with them. Saving 12 bucks isn't worth the hassle of changing the plugs twice.

 

I will install AC DelcoRapidfire #1 plugs (GM-25164639)the next time I install plugs.
1.) It is worth a few dollars to find out for myself if they are worth the extra cost.
2.) If they extend a tune up for 10,000 additional milescompared tothe standard AC Delco plugs, not having to changethe plugs for those extra mileswould be worth the extra cost.

The beer you spill during the weekcostsmore thanwhat the extra pricefor those plugs would be.
