9613 OE Fine Wire Double Iridium Spark Plug - Single

Put these in a 2006 Tacoma with 72k miles. Some say the Iridiums are good to 90k, but gas mileage and performance were dipping. Put these in and they fired right up and seemed to help perfomance a bit. Tacoma's don't get the greatest gas mileage and these may have picked it up 1or 2 mpg. Will have to run a few more tankfulls to see. If you are not sure you need to replace your plugs, you can order these to have on hand when you do. Check them carefully as they were loosely packed. I suggested to Amazon to pack them in peanuts rather than those air pillows. They were fine, but I would have liked them not to bounce around.

It’s an excellent part. But it’s a real pain in the neck, taking off the air and take. Watch some YouTube videos, and have a friend with you

I put these in my 2007 toyota fj cruiser... immediately notice the truck runs a lot more smoother and over the weeks also noticed a small improvement in gas milage .. Overall the truck runs better than before (this was compared to toyota dealership regular spark plugs) Not related but noteworthy.... (i do not run my tank to empty not a good idea living in the country) so all milage is to a 1/8 of a tank of gas.... My FJ is a premium fuel vehicle meaning it needs to run 91+ octane or higher. since the mandatory ethanol law all the gas stations in my area have changed to 87 octane. when I was running 91+ octane i was barely getting 250 miles to a tank of gas after the mandatory ethanol law I was forced to run 87 octane with 10% ethanol which I would only get 175 miles to a tank of gas... (huge drop was not happy about that) I put in the Bosch Iridium Fine Wire Spark Plug it boosted the gas milage to around 200 miles to a tank of gas.. then changed the oil from toyota's conventional oil to mobil one synthetic motor oil and a K&N air filter. Now I get 300 miles to a tank of gas which is a better rating than my truck had in the first place. 20 mpg HWY with an 1/8 of tank of gas to go.... :)

Got these plugs for two reasons. One is the longevity of the plug and less maintenance that i have to do in the future. two is I got a rebate which went from a good price to a great price. The plugs brought back quite a bit of performance and a little easier starts. Great plug-Go for it. 2005 Toyota Tacoma 4.0 liter - 105,000 miles

I had admired the design of this collective work via their development of hardware (power tools) so I had already been a fan of sorts. These worked out nicely with my new @hitachi ignition coils in the block of my 2007 @honda civic. I realized what power felt like when I dusted the cyber truck on 15 and mastered hydroplaning on my first attempt via FB and 286.

Planning on installing them next week, my car will only run good using these. If there a issue I will update my review and how the issue would be resolved if there happen to be one, but I don’t see that happening “knock on wood” Update it was a different brand I was recommended for that car, but they definitely helped increase HP when I changed them out today

Order arrived on time but only 3 of 4 were the right plug. All arrived in the same package and this odd plug was 2/3rds the size so don't understand how anyone could NOT notice that this plug didn't match the others. The odd one was in an individual package, labeled differently, different size listed on it and was significantly smaller. Wound up using one of the old plugs just to get the engine running. Not worth sending back but unsure how anyone could miss this and just disappointed in QC. Been using Amazon for years and unlike them to miss something this trivial. So far, the three that were the right plug seem to be working fine. Time will tell...

Good spark plugs great price work my 2013 lexus is 250
