BOSCH9621 OE Fine Wire Double Iridium Spark Plug - Single

I sent a failed product with a flag that was confirmed by the salesman.

It's very difficult to write a review on spark plugs, as its the type of product that is fitted and ignored or forgotten. All I can say is that the difference to have a new set of plugs fitted compared to those old plugs that have been coughing and spluttering over time, can be noticeable, and your Car will thank you for renewing them, maybe a few more miles to the gallon and less hiccups?. My only suggestion is to stick with a good quality plug such as Bosch, as they will outlive cheaper versions.

The picture in the ad is a way of what I found. It's like used or installed before as you can see from the picture the screw lines are not like new and not shiny like new and is not straight there are a little hits on it . Also the packing is very bad and two of it were opened, I did not install it yet but I was expecting to be looked like the pic in the ad. No Recommendation.

Works as it should, however the packaging it came in was a flimsy envelope, No protection for theses plugs, luckily none were damaged and they all work really well, my car BMW320i e46 loves these plugs, more responsive and runs nice and smooth.

I integrated this plug in my Puegeout 306 and it was no hassle and its working fine despite long journeys and daily running.

Worked a treat!! Saved me a lot of money that I would have spent getting a mechanic to do!
