Spark plug Bosch or OEM Toyota

As long as the Bosch ones match the factory specs then I’m sure they are fine as many other parts and sensors on these cars are made by Bosch.

Maintenance: 39th Oil Change (every 10K) and Tire Rotation, 13th Engine Air Filter, 13th Cabin Air Filter, 3 brake jobs, 3 coolant flushes, 2 spark plug changes w/carbon cleaning, no suspension work, no transmission service, 1 Break Down at 280K Due to a Design Flaw In The MGR Cable Which Powers The Hybrid System $5200, cat issue at 380K due to bad gas, no hybrid battery replacements in case you were wondering, does not consume oil

UPDATE: owners manual calls for replacement around 120k so I'm not that far behind i guess. Still went out and bought 4 new plugs and installed them. $80 at the dealer

Noticed before the LTFT was -6% and now its back to 0%.

Update: went Bosch for the plugs and ngk for the coils, the manufacturer plugs and coils were still in as if no one has touched them since the car was bought, I’m the third owner I believe. Each spark plug was toasted, easily double the recommended gap, and once I put the first two coils in (pulled code P0300, P0301,P0302) the problem entirely went away (coughing and sputtering exhaust, slow to accelerate, car shaking between 20-40 mph, rough starts) so I knew it was a go ahead for the rest of the coils. Feels like a whole new car all around, I can tell the engine is thanking me by what she’s putting out now ????

The best plug I found for a shovel is a Bosch Platinum WR8DP.

I got misfires with FD5POR RS2 plugs. Almost 10000kms on Bosch f2cs this year. Been working perfect for me

I'm running a Blue coil (only because the blue is cool), a compufire, and bosch plugs and wires. The blue coil is juat something to look at. You really wont notice a difference.

I then changed to a hotter plug the Bosch Platinum plugs and again gapped to .28. Once again the plugs fouled shortly after starting and driving for a few minutes.

Bosch finewires suck dong and AFAIK are not OE for anything even though they claim they're OE for practically every car on the road.

Bosch platinum are trash.
