vs
Spark plug Autolite or BERU
I've put about 100 miles on them and the car seems just as happy as ever. Went for a spirited drive today out in the hills and the car felt responsive and strong through the power range.
Pros: car felt responsive, strong power
Vehicle:
Subaru
Mileage: 160 km
Autolite a103 gapped to .055" will give you about a 5hp increase and last around 30,000 miles
Pros: 5hp increase, long lasting
Mileage: 30000 km
Part number: A103
Yup, these are great. Just be sure you gap them to APR's recommended gap of 0.024" ±0.002" or 0.6mm ±0.05mm. If you want 1 step colder plugs, not needed on your setup, but if you do for the future in Stage 2+. For 10$ more than the OEM NGK you can get the BERU.
Pros: great, step colder plugs
I found that it had Autolite Iridum spark plugs. They didn’t look bad and were gapped appropriately but I replaced them anyway with the recommended NGK spark plugs. Car has ran perfectly since then with no misfires or stuttering.
Pros: car ran perfectly
Cons: misfires and stuttering
Vehicle:
Saab
autolites 3923 platinumsgave me the same mpg as the expensive NGK platinum.....
Pros: same MPG as NGK
Cons: expensive
Part number: 3923
Do yourself a favor and throw Autolite plugs in the garbage.
Cons: bad quality
Definitely do NOT recommend Autolite spark plugs.
Cons: do NOT recommend
Don't use autolights. AC Delco for GMs & Motorcraft for Fords. Modern ignition systems are sensitive to plugs so I use whatever the OEM does (within reason)
Pros: AC Delco for GMs
Cons: Don't use autolights
Auto lights are trash, Bosch too. I can’t tell you how many times I get a misfire diag that the customer already put plugs in, only to find the garbage auto lights are the issue. A set of oem plugs always fixes it
Pros: OEM plugs always fixes
Cons: Auto lights are trash
I replaced the original ac Delco spark plugs (shown in picture, THEY LOOK BAD) and put with new auto light ones and changed the wire as well. However, after doing so, my truck has been running really rough, almost like it's cammed and misfiring, when its rolling in drive it like to have a little shake.
Cons: running really rough, misfiring
