SVO RPM Extender in nice working condition..was installed in my 1992 mustang..works great, AFR adjusting works perfect ....... will be sent to US from Costa Rica by tracked mail .. 150$ + shipping pay pal.. sent as it ..you get what you see in pics ..
Mine worked great and is still in a buddy's car (as far as I know). I used it for my LMAF in a KB Windsor setup before I went all 80mm (inlet plenum all the way to filter).
For those that aren't aware of what these are for:
This box "stretches" the resolution of a Mass Air Meter so that a meter that would otherwise be "pegged" can render a proper signal within the 5v range. In other words: You can read 1100+ CFM through a meter only capable reading 1000 CFM Maximum (within reason).
