630cc - Universal 60mm long

Took my 2004 Wrangler 4.0 from a rough idle to smooth as silk after installing these 630cc injectors. The EV14 design made them a direct drop-in with no adapter needed, and the 60mm length fit perfectly in the rail.

Finally got these swapped into my 99 Wrangler and the 60mm length fit perfectly in the stock rail without any spacers. Noticed the idle smoothed out right away, and the engine feels stronger under load than with the old injectors.

My 4.0 Wrangler’s been idling smoother since I swapped in this matched set of six—the EV14 tips made the spray pattern noticeably more even than the old singles. Took about an hour to fit, and the 60mm length lined up perfectly with the rail.
