Like all race car parts, your experience with other racers favorite parts may vary .
Keeping that in mind , I've had excellent results with the Moroso 40's . Treat them well , keep them clean and away from the headers ,and they will last several years.
I had old Moroso 80 ohm wires on my car for at least five years with no problems and only replaced them when I was chasing an ignition box problem.
Spend the money on the sleeves, well worth it.
