[Shotimes] 80mm MAF failure, ~$price? (HELP)

[Kevin & Cheryl Airth]

I run a stock 1993 Lincoln Mark VIII 80mm MAF with my stock SHO air box. I
had to turn the MAF 90 degrees to get it to fit. Works great but I have been
told that the MAF orientation is critical and that rotating it can throw
things off? More stealth too for the SCCA under hood safety inspections!!
