      Kit?

      Just follow the directions above, or if you have a 93-94 just go the the hardware store and get a hose connector and a couple hose clamps. It might cost a whole $3.

          Im not sure how much you will gain from it maybe a few HP. It just lowers the Intake Air temperature. This can be a hazard in cold areas where Ice can form on the intake, its not likely but posible,and freeze the throttle open. I have heard that it can give you up to 15 HP, but im on the fence about that one as the throttle body is very short and I believe the intake is tha part that heats up the air the most. Now if we could make a material that was impervious to heat, then make intakes out of it, then we would gain some HP

            Gain is 6.3HP and 7.1 lb-ft according to this dyno test at ws6.com. I've run without the coolant lines connected for 5 years, in temperatures as low as 0degF, and not experienced any problems with "icing". In 6 years on the various forums where the TB bypass has been discussed ad naseum I've hever heard of anyone having a problem. Maybe if you live north of the Arctic Circle....

              How would it ice up anyways when your driving because of the heat being put off by the motor. I think it would be more likely to get iced up and stick shut when turned off when the coolant lines are hooked up because their would be more heat held in it thus more condensation.

                Once the surface of the butterflies drops to 32degF or below, any moisture (humidity) in the air can freeze on them. You're more likely to have the blades at 32degF without the extra heat being input from the coolant. There isn't going to be any air moving over the blades when the engine is shut off, hence nothing to freeze.
