vs
Spark plug Autolite or OEM Audi
I find that chevies and dodges like autolite or delcos, fords i run motorcraft only, japanese stuff gets ngk's or bosch.
Note that decent spark plugs are hella expensive, but worth it due to lasting a lot longer than cheap $4 Autolite's.
Pros: long lasting
Cons: hella expensive
For what it's worth, here's my 2 cents on plugs and wires. I've read several threads here that indicated something along the lines of, \"YOU'D BETTER D@MN WELL USE NOTHING, I MEAN NOTHING BUT OEM BRAND PLUGS AND WIRES!!! THE CAR IS TUNED AT THE FACTORY USING THESE. IF YOU USE ANYTHING ELSE, YOUR CAR WILL RUN LIKE SH@T AND YOUR FUEL ECONOMY WILL BE TERRIBLE. YOU'VE BEEN WARNED!!!\" Fast forward to a few months ago when I had a breakdown an hour from home and was trying to figure out the problem. Because I was on the side of the road, I had to Uber it to the nearest parts store and take what they had on offer. If I remember right, the plugs were Autolite and the lightning hoses were Carquest (don't quote me here). No Bosch, no Bremi, etc. I was nervous about it, but hey, the car's 20 years old, so I wasn't worried about squeezing out the MAX performance. Guess what? It runs exactly the same as before and gets the same gas mileage.
Pros: runs exactly the same
Autolite is the brand I got through rock auto.
Pros: cheap price
These are Autolite plugs, not Motorcraft. Which means the plugs in this vehicle have been changed before, that probably has a little to do with why it was easier than usual to get these out. By the looks of the plugs and the lack of carbon buildup and corrosion (the two factors that cause these plugs to size the most) I'd say they weren't in there for a very long time either. Going by my experience with Autolite plugs in Fords (very little experience as I work on Euros mostly) if they don't start misfiring right away it's usually within a couple of months.
Pros: lack of carbon buildup
Cons: misfiring within months
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
As long as it’s not auto lite plugs you should be good. I’ve seen those things hinder 3 separate rigs from running right. Once one cracked 100 miles after installing them, half way through a trip we had to sop at autozone and replace plugs
Pros: other plugs should be good
Cons: hinder rigs from running
Mileage: 100 km
Don't even think the Autolite or Bosch last as long as Denso/NGK spark plugs.
Cons: do not last long
Vehicle:
Toyota Camry
