somekem or sdx
 

i was looking at ordering a set of 90hp injectors for my 96. how much hp could i get out of a set of 90hp. sdx has a core and the total comes to $600. somekem are 450. what does the core charge mean do i have to send in my old injectors and get back 150 bucks

yea the core charge is for your old injectors, when you send your old injectors back you will get the core charge back
