Affordable accurate torque wrench for spark plugs

I've seen few techs actually use one except to show off their tool to the customer in the shop. Just screw them in hand tight, then 1/2 to one more turn with the wrench for plugs with gaskets and 1/4 to 1/2 more without gaskets.
These work really nice. They're inexpensive, and you can put them in between the ratchet and your extension. The torque range is from 5.9 to 59 ft. lbs.

Some bicycle torque wrenches can hit that.
I'm sure there is something in your budget. $30 to $40 gets you a clicker, $120 gets you a Tekton Split Beam.
Of course the sky's the limit. Get a nice tool and enjoy it.

For that low, I'd also recommend a 1/4" from lowes/homedepot/harborfreight, and if it doesn't have ft lbs, just use a ftlbs to inlbs online calculator. https://online-calculator.org/13-foot-pounds-to-inch-pounds

My ACdelco 3/8 and 1/2" digital torque adapter are very accurate. I'd wager that the HF one is plenty good and accurate and makes you wonder if all the 'brands' run down the same Asian assembly line and just have different plastic cases.
Is $101 affordable? Norbar has several excellent torque wrenches that meet your requirements, such as this 3/8" drive 8-35 ft-lb model:

With more and more engines being made from all aluminum a good lower value and accurate torque wrench is almost a must have tool. We read about all the Icon and other brands that are in the $100 range, these tools have no replacement parts or service available for them. The first one here is a...

The Norbar every time.
I would agree on the HF's 1/2 torque wrench, but not on the 1/4 and 3/8. Bad experience with them.
Does the spark plug instructions give a torque angle? I find this much easier considering many engines make it impossible to use a wrench on some of the plugs.
I have Harbor Freights 1/4", 3/8" and 1/2" click torque wrenches. I feel like I loaded up on coupons and got them for $10 each several years ago. I've definitely used the 3/8" for spark plugs.
Just back them down after each use and they should stay accurate for many years.

I have never found an engine where it was impossible to use a torque wrench on the spark plugs.

I have no idea how you would operate a torque wrench on the back bank of spark plugs on my old 1MZ-FE. But maybe a real mechanic could do so although I wouldn’t know why. Torque angle is better anyway as it is independent of whether you’ve used anti-seize or not.
