The better durability is just my experience, Other than that i have no info on wether they are more durable.
My plan wasn't to gain performance, or consistency (though both would be a bonus), I wanted to consolidate parts. Instead of 5 or 6 of two different plugs, I can have 6 to 8 of one. I know the turbo's are more expensive, but more parts that are universal, the less you have to carry. Besides if i wanted performance, I can port it to get what i want. I chose not to, because you don't really need a lot of power in stadium truck
