84-91 13B N/A Rx7 Atkins Designed Six Port Actuator Valve Kit (ARE113)
These fit a 1984-1991 13B Non Turbo Six Port Engine.
Expect about a 2hp gain.
Enough for one engine, stock actuators have a dead spot at the end of them where the intake air hits a dead spot and cavitates instead of continuing into the engine. Our intake actuators fix this problem by creating a smooth transition from intake to engine and generating more power.
Don't waste time gluing inserts into your actuators that have the possibility to fall out, just put new and better actuators in and be done with it.
