Red Bullet Solenoi purchased new and used for less than 20k miles. Came out of my 2012 Prius. Previous FS post states it is the same as Quantum Solenoid I which I would think is accurate. Super easy 5 minute install for a better driving experience for your daily commuter for sure. Throttle response and gas mileage were improved for me. Better acceleration with the power mode for sure. I’m looking to upgrade to the Quantum Solenoid Track Edition. Say what you want but it made an improvement to me and I drive a lot of miles. It is designed for the 2zr-fxe engine. Gen 3 Prius, Gen 4 Prius, Gen 3 Plug-in, Prius V and CT200h. $170 shipped in the US or pickup for $160 in zip codes 92308 or 90012 DTLA
