I made an air duct system, just like the one sold to keep the front brakes cool. Went to home depot and bought a flexable wet dry vac hose and routed it to the blower. Of course it's only effective when the car is moving.

(2) 4" SS Screw Clamps

Procedure:

On the passenger side rear storage compartment, remove the storage tray and the cloth storage compartment lining.

Remove the 8 Phillips screws supporting the storage compartment lid assembly and remove the lid assembly.

Measure and drill holes in aluminum bar to match holes in battery storage tray and mark and drill holes in bottom of storage compartment. Place battery tray in compartment, using bolts, and washer and secure aluminum bar on underside of compartment with nuts and washers. Mount battery with posts towards the drive shaft rather then towards outside side. Install terminal corrosion protection.

Drill two holes for battery cables in side of storage compartment for battery cable egress.

Measure, mark and drill to holes in side of storage compartment for circuit breaker.

Mount battery in tray.

Mount circuit breaker on side of storage compartment and secure with bolts.

Put black automotive wire protector over positive leads. Run positive lead thru storage compartment access hold, over c-beam (thingy the drive shaft is surrounded by and over to driver's side in front of rear wheels. Secure with tie wraps to existing wiring harness that runs over the c-beam.

Remove front battery access panel, remove front battery.

Use an electric wire fish tape to fish positive electrical lead through rocker panels on driver side and into engine battery compartment.

Run ground wire from negative top battery post, thru access hole, and ground to frame.

Do not remove original battery tray. Remove the back most bolt from the battery tray and use this bolt to support the new positive insulated battery post. Connect original battery post to new battery lead on the insulated post. Cover with provided insulating cover.

Tie wrap everything neatly.

Air Duct Installation:

Remove existing air filter from ATI unit.
For ease in installation, remove wiring harness from cruise control and two vacuum lines from cruse control to ease installation. Disconnect wiring harness for cable that runs along rear inside of forward wheel well.

Fish new flexible air duct under cruse control support beam, under master cylinder, and up and around into ATI air intake. Secure with screw clamp. Cut air duct to length. Install air filter to end of duct and secure with screw clamp. Place on battery tray.

Reinstall battery access panel. Reconnect all vacuum lines, and electrical harnesses.

Try coating your header's. Swain is the best to reduce heat transfer. http://www.swaintech.com/

In an efferot to reduce heat exposure of the alternator, I tried header wrap with disapointing results. It is not possible to maintain less than a 1/2 inch overlap between wrap windings around the header bends. If there is too much overlap, you'll destroy the headers by overheating them.

My solution was cheap and it worked great. The grocery store aluminum foil that comes in the wide rolls has a greater thickness than the short rolls. It is pretty sturdy stuff. I wrapped each header tube in foil. It has been in place for over a year and is still in great shape. I did not even have to use metal ties to hold it in place. It was very effective at reducing radiant heat.

I'm wanting to coat my LPE headers, but not wanting to spend the $225-$275 that Swain charges. I've searched for a ceramic paint with no luck. I think I'm going buy and crush up some floor tile to a powder and then mix it with a high temp paint. I could coat them myself for less than $20 then.

I think you should add that mod to your sig :cheers: :lol:

A few years ago I bought a gallon of high temp coating that you paint on then heat to 350 df for a couple hours. So far so good on my headers. Only use about a quart and will someday do the rest of the exhaust system.
