Spark plug Autolite or Denso

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.

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.

I like ac delco. But I recently used denso tt fine wire plugs I two different ls engines. What a difference in power. And gas mileage.

I just replaced mine, at 80k, with Denso PLatinums. The same brand as the stock plugs.

Autolite is the brand I got through rock auto.

No discernible difference to me, positive or negative. But since I am running APR stage 1, I followed APR's recommendation.

I tried Denso once. I took Denso’s out and replaced them with Denso’s. They ran for 500 miles and quit.

I wouldn’t put autolite plugs even in my lawnmower. NGK or Denso only.

Im running denso step 2 cold plugs from bms website and tbh i regret not going with the hks plugs
