Fuel pressure regulator - $400 from Rotax or $22 online

I’m going to say yes, but it does not say Rotax 😬

Neither does the one that comes from Rotax. It says Bosch. 

I bought a new one last year when I did my 5 year, and I think it was about $320.00 from a Rotax distributor at the time.  And you are correct, it did say Bosch, not Rotax.  I understand the cost of stocking parts, and the need to make a profit, but when you see 1700% markup its hard not to feel insulted.  

I feel your pain. It’s beyond absurd. That’s why more people should know this so they don’t buy the same part from Rotax. 

I definitely use original Rotax parts in my maintenance work. But it doesn't make sense to buy the following from Rotax.

You may use Bosch 0 280 160 557 instead of Rotax 889262 fuel pressure regulator in iS engine.

Also, Bosch 0 450 905 021 instead of 874060 fuel filter.

There is also a Bosch equivalent of the 966482 throttle position sensor for 914s, but I can't think of the code right now. It can be found with a little searching. Bosch much, much cheaper and 100% identical.

I haven't found a complete solution to the dual ground spark plug yet... :)
