So i got a set of these Iridium plugs and installed them on my truck.
They went in with out a hiccup the threads matched exactly unlike some of the other brands out there. They were pre gapped and just went right in. Even though the mileage is low on my truck I can see it idles smoother and accelerates smoother and faster.

Maybe after a couple of tanks they might show some mileage increases.

I'd like to thanks Bosch for sending me these plugs as they truly work great!

 

so its faster with plugs? What were you running before where you had thread issues?

 

 

I dont wanna say it's faster... But runs alot smoother! I have factory plugs in it now.... however i have had plug problems on previously and was amazed with the fitment!

 

so you got the bosch plugs, put them in and ran it, then swapped them out for the stock plugs again? just trying to understand whats going on!

 

Sorry I mis typed. I swapped out factory plugs for the Bosch!
I was skeptical because I've swapped factory plugs for brand X before and had crappy figment issues but these fit great! And being they are pre gapped, I checked them all as I'm used to it, but they were right went right in and run super smooth.

 

Someone just posted an issue about these plugs causing their truck to run like ****, swapped to originals and it ran fine. Could mean many things. He also stated he didn't change #8 because it was a PITA...

 

I know Fusion plugs will do that, but Iridiums are about the same as A/C Delco which are OEM.

 

Wouldn't use Bosch plugs if they came with a twenty dollar bill. Every week we get at least 1 car with a misfire caused by Bosch or E3 gimick plugs. The OEM plugs are awesome plugs so why change them?

 

These are great so far so good!
