Excellent choice for 3.5 ecoboost engine!
Bought these for my 2021 F150 3.5L ecoboost, and noticed an immediate improvement in starting and smoother engine idle. I had 62,000 miles on my truck, and they definitely needed changing!

Champion RDZ19H spark plug for Ryobi 990r trimmer does the job
I had trouble finding the Champion RDZ19H spark plug required by my older Ryobi 990r string trimmer. Lowes had a non-Champion replacement product whose cross reference guide identified it as a replacement for the plug in my trimmer, but I bought it and found that it was not compatible. I recommend that you pull the spark plug and purchase or order an exact match for the part number on your plug. The replacement RDZ19H greatly improved the starting and running of my trimmer. I'll probably order a spare to keep on hand for when my trimmer starts acting up again.

Direct fitment
Haven't had a chance to use the equipment yet but I believe it will be fine as Champion products has worked good in all my small engine applications

Lifesaver as nowhere locally had this in stock.
It seems like the ONLY use for this spark plug is for the little edger (sold under a few different brands). I needed one and after checking half a dozen places locally absolutely nowhere had this spark plug. Amazon for the save getting it to me the next day!

Always use Champion if the Manufacturer recommends it!
Learned my lesson the hard way. I initially purchased a cheaply made generic brand locally because i couldn't find this Champion RDZ19H anywhere around. When I installed the properly gapped knock-off into my 4-cycle weed trimmer I darn near broke the starting rope pulling endlessly for an engine that wouldn't start. Well luckily I kept the original 3 year old and kinda oily RDZ19H and installed it back in the trimmer and four pulls later the engine started and ran fine. Naturally I'm starting to use Amazon more and more as they are convenient and Fast at shipping stuff and getting it "right" every time. Best part is the Champion was approx. $1.50 cheaper than the generic spark plug.
