The carbon duct intake system that the ultimate efficiency was high density air intake was pursued. Will fit all 96-00 Civic with B16A and B16B Type R ENGINES. Might Fit other CX/DX/EX with Small Modifications.
The best model of the intake system that intake efficiency and total balance were pursued to the limit.
How do we shut off "heat" which has a big influence on the performance of the engine? From among the various possibilities, we have continued the trial in every approach. However, the method that we arrived at in order to aim at "perfection" was to completely cut off the air introduction path from the engine room. In fact, normal(genuine) is this concept definitely. However, the normal state cannot become "perfection" because it is designed in various restrictions. The air intake system which gave the best performance and quality worthy of the name of the air intake specialist, is this “RAM AIR SYSTEM”. As for this, the efficiency was taken in consideration of the top priority efficiency, without being influenced by the above restrictions.
Here is how it looks like installed:
