Spark plug Bosch or Autolite

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.

I have autolite xp in the van. $100 for 6 ngk, $90 for denso with a van with 250k miles. Everyone says there crap, but it runs great.

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 always had issues when I used any plugs other than Bosch Iridium or Platinum. You can even try Bosch copper plugs if you find the right heat and size. They're usually cheaper and better, but don't last very long... like 10k miles.

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.

autolites were fine 100 years ago

now stick with NGK or whatever OEM was. its not worth it to be fudging around and what little your gonna save may be burned up in less MPG using some other plug.

I've had nothing but bad luck with Autolite brand.

I have a poor running Audi in the shop now. While it needs more than plugs, it has autolites.

the autolites are bottom of the barrel, i've only used them once when i was young and dumb and ofc they busted while trying to repair and remove after.
