1500cc - F-Series, GT, Shelby GT350

These things are huge, I mean physically big compared to the stockers, but they bolted right up to the rail on my GT. The idle is actually decent for 1500cc, and the matched set means I didn't have to fuss with any of them tuning-wise.

Dead-on flow rates across all 8 on my 2017 GT350—the EV14 body design made them a direct swap without any adapter headaches. Pulled the old rails and these seated perfectly, and the car's been running crisp at idle and WOT since.

Swapped these into my GT350 and the idle smoothed out immediately, even with the huge flow rate. The EV14 design fits the factory rail without any adapters, which saved me a lot of headache.
