You say the evolution will outlast an OS ABN engine??? Evolution has been around less than 5 years. Can you see the future? Saying an evolution will outlast an OS is a rash statement not based on fact. There is no precedent. OS has been making ABC(ABN) engines for almost 30 years. I have an old OS45FSR ABC that I bought in 1980 and it is still going strong. Only thing ever replaced was the bearings and they lasted almost 20 years. I also have have several other FSR series engine at least 20 years old that are running strong.

Next to the LC3 plug which is a car plug, the #8 is the hottest plug OS makes and is as hot as or hotter than the Tower plug. It is equal to the Enya #3 which is Enya's hottest plug.
