So I am looking on the Summit website and notice there are 3 different throttle bodies that appear to be direct fit. They are the 112-505, 112-507 & 112-509. What is the difference between these three and which would you recommend?

Here you go. See for yourself.

112-505 has a Natural finish while 112-507 and 112-509 have a Clear anodized finish. Also 112-505 has a TPS sensor included.

I had already compared the three on Summit and did not notice the TPS, but why is the 112-509 and 112-507 $30 difference? They appear to be the same part......?

Thanks,
TOM B

 

The 507 is for a L98 motor (TPI), the 509 is for the LT1. The 505 is for a 92-93 LT1 car that still uses the kick down cable on the transmission.

If you have a 92-93 Corvette or 93 F body, order the 505. If you have a 94-97 LT1, order the 509.
