Just came from the dealer, thought I would look into having them change out my plugs, but my service rep was out to lunch. So I went in to see how much plugs would be to do it myself. OMG $17.30 each, is this what those of you that have changed your plugs paid? If not, please help and tell me where you got them.

 

That's so expensive dude i would never pay that much, if your looking for an ignition upgrade check out the plasma booster on www.f150store.com that is supposed to produce more power. Answer to ur question i don't think there is anyone selling spark plugs for our truck other than our dealer [could be wrong] as i have never seen any. Just keep looking round but personally iw ould not pay 17 bucks per each spark plug.

 

Im pretty sure thats what everyone was paying unless they had a hookup at the dealer.

 

I just called AutoZone, they did not have them in stock but could get them over night. Autolites for $11.99 each.

 

Here is where I got mine for $7.53 each: Plugs

Someone else said they got theirs from RockAuto.com for $6.00 each with free shipping.

 

Check "The Spark Plug Thread". I know it's long and painful but there's a few links in there for places to get them for under $10 each.
