Spark plugs and spark plug wires GMC seirra 2008 SLE 5.3

[mike66]

My GMC sierra 2008 vortec 5.3 has done 165000 Kms , looking for some info on spark plug and spark plug wires , checked with the dealer here in Calgary and the wire set is $219.00 , each spark plug is $15.99 (Canadian) , pretty pricy , other than AC delco are there any other options? I usually prefer OEM stuff. Also could any one tell me what is the torque for the spark plug.

 

Thanks for your time.

Stick with the OEM plugs for sure. As for wires, good quality aftermarket will work fine.

 

I have had no luck with aftermarket plugs in late model, stock gm products. Aways seem to get misfire codes 20-30k miles later with anything but oem.

Plenty of places to buy AC Delco besides a dealer. NGK is another plug choice

Online from Rockauto is quite cost effective.

Any Napa dealer sells AC Delco parts nowdays and the plugs will easily be half of what GM wants for them or less. Stick with the oem iridiums in my opinion as they work very well..... a good chance your originals are still fine as the ones that came out of my 05 6 liter were still good at around 200000 kms. I swapped them but still there was nothing wrong with the original plugs. For wires I just went with MSD 8.5 mm wires from Mopac for around $90. A lot less resistance than the oem's and no noise issues with the radio or what have you.

Dont know if I'm late or whatnot.

 

I recently did my plugs but did not change my wires. Being an electrician I pulled out my meter and tested the resistance on each one. I have 122,000 kms on mine and they were all well within the proper parameters. You can get the parameters from the dealership. Mine, I believe, were around 900-1300 Ohms.

^{Thanks for the input guys. I checked ebay , can get a set of AC DELCO iridium's plugs with shipping to Canada for around 70 Canadian dollars and wires too for less than 100 Canadian dollars. May go for these. Appreciate your time}
