Quick question for anyone who can help me out.

According to some people Early MY99's acctualy have different Air Flow Sensors from Late MY 99's (And models following all have smaller ones as well)

Is this True or False?

Moving on, Can I purchase one of these smaller ones from a more recent model rex and fit it into my early MY99 without causing dramas with the ECU etc.

If anyone can help me out with that I would greatly appreciate it!!

Thanks!

They're not interchangable.
And old ones, 97/98 are dearer than later ones 99/00.

yep, i found that out!! i paid $690 trade but they're $820+ retail where as the later ones go for around $200 - $250!!

also told they are not interchangable.

on the upside. the my98 and previous AFMs are alot more durable than my99/00 AFMs

I bet you had to buy the AFM sensor and whole inlet pipe for that money.

99/00 ones used to be that stupid amount until Subaru finally woke up after many complaints and decided to just sell the AFM Sensor.

there was a newer version the 'green dot' version since the original 99 afm but thats been standard for ages now.

nope, just the AFM that bolts to the airbox, no inlet pipes at all!!
