I have had flowmatched MSD 50# injectors before and the writing etched on the side ranged from 44.1-44.3.

On these 160# injectors, they range from 110 to 177! 67# difference???

 

were you sold a 'matched' set? should be 3% max difference or so i can't remember the standard

 

I thought the etching on the side ment they were matched. Or does this mean they were just flowed?

Even if they are not matched is it normal to have that much difference?

Anyone know what brand these are?

 

They are supposed to be +/- 5% of the #160 from the factory .

 

which is like a 8 psi swing.. i would NOT put those in your car and honestly wouldnt even ask for a 'good' set.. i would drop that vendor all together and take your money elsewhere. (as long as you specifically purchased a matched set, and not just a flowed set)

 

Kinsler should be able to set you straight Andy.
