if there is anyone interested in getting a little more power out of their EF DPFI i have a little tip. i found this to be very interesting. there is a spacer between the intake manifold and the throttle body. the one on the dx is alot biger than the one on the std civic. i dont know any hp or tq gains but it should be subtantial. there is a big difference between the two



ENJOY
