A little difficult to mount in a Convertible but works great. An ideal attention getter. Wife says I need to install another in my grand-daughter's Mini hatchback.
I bought Denso Iridium Colder spark plugs recently and found out that they are a horrible product to use. Wish that Outmotoring would allow customer reviews on products, that way we the consumer wouldn't have to worry able destroying our vehicles by adding sh!# parts. Why even sell this brand of spark plug if they have a bad reputation of popping out and destroying the threading!
