I couldn't find the MPX4250AP at digikey. have a link?

I don't get why ia's mod would pass emission and some other mod wouldn't. 
please explain...when i last went to emissions they just bring it up to 
50mph on the rollers. As long as they don't take it up to 1.4 bar, there 
would be no apparent difference. Maybe I'm missing yer point....
