New member here, figured this might be a good place to ask my question. Have an 89 integra chassis, and a stock 94 B18 GSR motor. The issue i have is the IAC on the back of the intake manifold is too large and is hitting on the firewall even after massaging it with some hammer action. Are there some aftermarket manifolds that are physically shorter in the runners to pull the manifold away from the firewall. Thanks for any help
