No you need 928 105 530 04

Our test gears have now completed over 13500 miles on a supercharged car using a Racing Timing Belt with no wear.

Won't they eat into the belt causing the belt to break?

Roger,

Does that mean we'll see them next month?

I'm down for a pair ASAP.

I suppose that makes sense, could they cause excessive belt vibration/flutter too?

Too bad 928MS doesn't make cam gears for 16v engines.

Where can you purchase the OEM porsche ones, I thought they were NLA?

My gears looked similar to these when we did my TB/WP job. I should have replaced them then, but didnt know any better. Replaced the original belt with the Gates Racing Belt and the Porkensioner - minus the air pump. No change in gear wear in 30K miles. I think the stock tensioner & lack of maintenance contributed to excessive belt flapping & was the primary culprit to early gear wear. Still, I'll be replacing my cam gears in 10K miles or so...
