Owner reviews for spark plug

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 had good luck with ngk bp6hs, Bosch w8Bc, champion l87yc and renault oem short thread (yes, really.) plugs. Bosch w8ac used to be good but i had some arrive not working out of the box recently so I'm now avoiding them.

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.

switched to the back to the motorcraft spark plugs $15 a piece fixed it for a while

I have installed brand new NGK sparkplugs and Bosh ignition coils...but the cylinder 1 misfire does not move or is resolved at all.

Get rid of those ASAP. These are prone to breaking their ground straps. Myself and many many others have fell victim to this.
