512TR & M, 456, 550 throttle body o-ring, Ferrari P/N: 142934 McMaster P/N:9263K749, Generically: Viton Fluoroelastomer metric o-ring, 75mm ID, 3mm width (BTW, not much money to be saved by purchasing from McMaster as they're $4.41 each in a pack of 2. Daniel's price is $4.55 each. So McMaster would only be an alternate source)
finally worked out how to attch a document, yes I'm slow! This is produced by manually cross seaching the Bosch catalogue for other makes and models that used the same Bosch parts as the 550. I have found this helpful in seraching the internet for other parts sources. Nigel Image Unavailable, Please Login
Right side TPS Ferrari P/N: 172750 Bosch P/N: 0 280 122 004 Left side TPS Ferrari P/N: 158170 Bosch P/N: 0 280 122 005 Note, these numbers and their sides are as per the Ferrari diagrams, however, I believe they're reversed. The sensor on my car's right bank is the Bosch 0 280 122 005, which is the expensive one (dual connector). The one on the left bank of the car is the cheaper one (single connector).

Is it Ferrari 157991, which is supposed to be a 30a relay for LH & RH radiator fans, but in reality, it's a 50a Bosch relay? Here's the cross I found to Tyco and they're available @ Waytek and others with the Tyco P/N: Bosch P/N: 0332019103 Tyco P/N: V23234B0001X001 HIGH CURRENT MINI RELAY 12V 50A SPST V23234B0001X001 - 75301
The early 456's use a TEVES electrical / hydraulic brake booster system. I believe the 456 hydraulic accumulator and pressure switch are interchangable with parts supplied by AC Delco (#25528382 - accumulator) and #25533700 pressure switch) which are the parts most prone to failure. However I have not personally verified this.
Yes, Ferrari part number 157991. Bosch datasheets say good for 50A. Used for 550 radiator fan, a/c , headlights, etc. I understand Tyco took over the Bosch relay business some years ago. Thanks for Tyco equivalent and link, is the Tyco quality as good? Ron
Ron, I don't think the present Tyco products are as good as the "old" Bosch, but they're better quality than the "new" stuff that Bosch sell, if that makes sense?
John, Bought a bag of 5 relays from Tyco at $7 each. Seem to work fine. I replaced the hard working relays like dim and main beam lights, a/c and now I have a few spare e.g. for radiator fans if need be. Regards, Ron

John- The good Tyco relays work fine. The old Siemens relays had some serious problems, like the first one used for early F1 pump relays.

Not that this is very useful, but... Ferrari part # 183758 seems to be interchangeable w/ Ferrari # 226484 (I think the latter is sold in Europe, I got it cheap here on Ebay). I installed the 226484 in a 95 456 GT.... works just like the original and, specs tested identically. Anybody know if there's a difference? And, based on the above, one can speculate that any 456/550/575 thermostat will work in any of these cars, even though there are different part #'s???? This might be useful to non-USA owners... Thermostat prices vary widely.... Image Unavailable, Please Login
THERMOSTAT Part No. 226484. Superceded From Part No. 183758. http://www.superformance.co.uk/a-v12m/cooling.htm
That was my confusion, Bernard: ....You can pay 74 Pounds for 183758... or 175 Pounds for 226484??? Or, are you saying you can't get 183758 anymore? I have one tested to work, if they're now worth $263USD? Regards....Mark Image Unavailable, Please Login

Yes, Bernard: Eurospares is even more confusing. You can get a 183758 or pay 3 times the price for a 226484? Hum? Guess I can say I have the updated $350USD thermostat in my car. Image Unavailable, Please Login
My tire pressure sensor readings are getting a little wonky..... Is there an alternative to the (no surprise here) expensive Ferrari units ? I am planning on a trye change soon, and it's easier to swap out the sensors when the tyres are off. Thanks, Scott
Assuming your 575M is a US version, you need Huf Beru RDE004 315 MHz sensors in dark brown (earlier generations were dark gray). Available from TireRack or Amazon. Last time I checked they were $105 each through Amazon and their subcontractor. You can buy the valve rebuild kits, too, which I recommend.
Bosch fuel pumps for 456 and possibly 550 can be replaced with one of these which is identical and seems to be more readily available. As sold by Eurospares for the 456 but half the price on e-bay. Image Unavailable, Please Login
