im sure ive head some somewhere... but its a noticeable difference for the neons... the 19#'s i noticed nothing power wise and about the same with fuel mileage... they have 4 holes instead of one so better atomization...

I hate to say this... but I noticed no gains from the 784's in my 99. Fuel economy is still terrible, power may be a bit smoother, but its not much.
I even cleaned and tested them properly before I installed them.
Ultrasonic cleaned and everything.
Oh well. It was worth a try I suppose... can't help but be disappointed.

I got some explorer upr/lwr intakes that i decast and polish then resell to the mustangers as an upgrade over stock. Its the same as a gt40 int but about 10 cfm less flow.
anyway i pulled like 5 of these out of the j-yard and i have prolly 16 or so injectors (have to check). they are the yellows. will these plug right in to my 99?
I too have been searching the hell out of this,but did not find much about 99 up.
thanks.
