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.

Pros: good quality oil, reliable air filter

Cons: champion plugs not recommended, fram oil filter

Vehicle: Ford

Mileage: 120000 km

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.

Pros: best price, OEM brand

Vehicle: Toyota

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

Pros: cheap, around $5

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

Pros: longest life, easy to replace

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).

Pros: long lifespan, good durability

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.

Pros: trusted quality, mechanic recommended

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.

Cons: terrible condition, corroded diode, oil on threads, frequent replacement, expensive
