I ducted air with galvanized sheet metal up from the front grill to the opening for original airbox, behind headlight.

Then I made a plastic box to seal off the heat from under the hood from getting into the K&N.

You DO NOT want hot air going into the air cleaner, it cause HP loss !!!

Of these mods, what is legal in CA? I really don't want to pay $50. or so for a stock rubber intake hose to replace the damaged on I have, if I can install a better flowing intake pipe from my air-box.
