550cc - Universal 60mm long

The EV14 design made these a direct plug-and-play upgrade for my Jeep's stock harness, no adapters needed. After installing the 550cc set, the idle smoothed out noticeably over the tired old injectors. Definitely woke up the mid-range on my 4.0L.

Put these in my '07 Wrangler 3.8L last weekend, and the idle smoothed out immediately compared to the old ones. The EV14 design is noticeably smaller, which helped with access in the tight engine bay. Car feels more responsive on the highway now.

Swapped these into my 2004 Wrangler 4.0L and the 60mm length was a perfect fit for the stock fuel rail. The 550cc flow rate gave a noticeable improvement in throttle response during my morning commute.
