MTI X1 cam
It'll depend on too many factors like your spring choice, driving style, time you spend at the track or on the dyno, etc.
Get some good ones, and there's no reason (if installed correctly) they shouldn't last until your ready to change them for some other reason.

shh let the big boys talk.
I can say ive had this cam for about 9 months now. Dialy driven, autoX, 1/4, freeway racing.. makes a nice LONG tq band and power up to 6800 if you wanna spin her that high. I get comments all the time of its "old school" sound. MPG didnt suffer much either.
I've put 7,000 miles on since install and its a daily driver. Manners are pretty good, it will hunt for idle occassionally on hot start and buck at low rpms sometimes (only requires briefly engaging the clutch to settle it down).
I plan to have the springs changed after 15,000 or so miles, just for insurance although MTI told me they could probably go to 30,000 miles.
Great cam, definitely no regrets!
