changed out the spark plugs, all except for cyl 1 had crazy looking plugs. Used Bosch platinum 6704 cleared up the CEL and also the stability and TC lights no longer flash so somehow that was connected I guess.
Autolite plugs work fine in my Toyotas.
For iridium spark plug. Do NOT gap them. I have bosch double iridium spark plugs and over 120K miles now. Still goes strong.
My car has Bosch Double Iridium spark plugs. Over 120K miles now still go strong.
I don't say for 100% sure but my understanding is that Bosch and NGK are the ones you should use
I replaced the spark plug with an Auto Lite spark plug. Engine light went away but still runs rough and misfire on acceleration.
My s2000 ate the Bosch plugs I put in, which were rated for the car/f20.
I changed the spark plugs on my X5 with Bosch ones. My mechanic showed signs of being upset with me for not bringing the genuine BMW ones... Fast forward to a week ago - the car throws a check engine light and OBD scan shows faulty oxygen sensor heater circuit. My mechanic linked this to the Bosch plugs, suggesting they might not be the correct type. I ended up replacing them with genuine BMW plugs and an O2 sensor, which cleared the codes and improved power. My learning is that Bosch has many SKUs, and it's hard to ensure the exact OE part number, potentially leading to incorrect plug types (e.g., 'double platinum' instead of 'laser iridium') for BMW, costing more in the long run.
autolite, worst spark plugs in the world. I'm tired of customers asking for cheaper plugs and they cause misfire
Autolite are for cars your selling there super cheap and garbage
