Spark plug NGK or Autolite

Every one of my internal combustion engines (3 cars, 2 motorcycles, zero turn mower, has NGK plugs.

It's hard to go wrong with NGK spark plugs on Japanese vehicles. That's what I've always done with great luck.

I'd recommend getting either spark plug yourself at a parts store, they last much longer than platinum spark plugs and offer more performance. plus the rutheniums, if available for your model year, offer slightly better fuel economy as well. if you want the ones with the longest longevity and best performance I'd get iridium high ignitability, but those can be costly. definitely go with NGK. bosch are also decent and denso are usually oem but I personally prefer ngk.

I put NGK B5HS plugs in mine, no complaints so far.

Almost any spark plug is better than the Torch it comes with. The recomended is the NGK BP7ES, but is not made any more, many use the BPR7ES without issue, which is a resistor plug, but the manual specifically says to not use a resistor plug. I am using an [Autolite AR52 plug](https://a.co/d/7Z3keDh), it crosses with the stock Torch and NGK BP7ES and is a non-resistor plug. Many people hate Autolite plugs, but I have been using them for years in other vehicles and never had an issue, and so far it is working just fine in my 11500.

Torch F7tc took 3-5 attempts to crank. This NGK paired w my Wgen11500 cranks first try every time. Very pleased.

RX7 mark 1. Wouldn't rev past 6000 with Champions, replaced with NGK and sang like an angel. It's not the price, it's the quality.

the cheap, no name one it came with was doing the exact same thing as the new NGK one I put in (and properly gapped) to try and remedy the issue.

Make sure if you purchase spark plugs that it is not Auto Light. They tend to mess your vehicle up more and not work well with Toyotas.

Ngks are fine but be careful with them. I myself ran these and changed them at 10k intervals. I met someone at a car meet who recommended 5k intervals w these n I didn’t understand till my engine was gone. They can foul up and break inside the cylinder. Granted in my case it was my fault but it’s happened a few times w other ppl.
