Spark plug Denso or Motorcraft
Reviews
I bought the absolute cheapest plugs available ($1.50/plug), and they are branded "Denso Toyota Iridium" - I assume fakes, but my magnifying glass does seem to show an iridium tip, and they work great.
Pros: work great
I did Denso 3297 from RockAuto. They work great.
Pros: they work great
Part number: 3297
I've always used the Denso SK20R11 plugs in mine and been pleased.
Pros: been pleased
Part number: SK20R11
Denso iridium plugs, no more no less and no exceptions.

denso iridium. do them and they’ll be good for another 200k km or more
Pros: good for 200k km
Mileage: 200000 km

Has anyone tried the Motorcraft SP594 plugs? They supercede from the SP542, which is said to be a 1 step colder plug for our cars. Currently running NGK 6510s but i think i got a "fake" set as i paid like $30 from Amazon for them. The SP594s I can get for $41 from Ford... so anyone have good results?
Part number: SP594
I got some phony Denso marked spark plugs
Cons: phony spark plugs
Porcelain tip fell off one Denso spark plug in cylinder 1. Doing less the 200km distance. Motor is f@$ked.
Cons: motor is f@$ked
Mileage: 200 km
