Owner reviews for spark plug

I just got a new to me 2016 f150 with 120k. Did air filter, cabin filter, spark plugs (had a misfire) and boots and oil change. I used champion plugs but most reccomend OEM. Got a wix air filter and a fram oil filter. I used full synthetic 5W-20 Valvoline R&P oil. Use rock auto for parts if possible.

use NGK spark plugs, the best ones are the PFR6Q

Denso or NGk for anything and everything preferably dual ground spark plugs. I would get them rockauto as they have the best price and you can get the OEM brand.

Get the right dual electrode spark plugs, Denso or equivalent. They’re cheap, around $5 per plug.

Spark plugs are only $15 for Denso iridium plugs (providing the longest life) and they take no more than 20 minutes to replace them.

The OEM plugs are iridium and are good for 120k miles, per Toyota. I paid about $16 per from a dealership (which I was happy to do, because its a job I dont want to be doing again in 50k miles).

OEM Mopar plugs (16) ran about $350... My trusted independent mechanic stated he would only use the OEM plugs for this model instead of Autozone cheaper plugs. I trusted his judgement.

NGK all the way, 100% of the time.

I don't trust hks, too many copycat them.

It has 90k miles and we've been having issues with spark plugs. 3 months ago we replaced them after a cylinder 2 misfire. About a month ago same thing. Both times they looked terrible. Diode was all corroded and the threads had oil on them. Last night on my way to work cylinder 2 misfire came back. Anyway, I always use iridium ngk plugs as thats what's recommended but they are getting expensive having to buy them every month or 2.

Autolite are for cars your selling there super cheap and garbage
