as some of you know, I installed a K&N cone filter. Now I need to figure out how to make my heatshield. Here is a pict of the JWT, as you can tell, the sheild is fairly small, and totally open towards the back and sits pretty close to the filter.
Below the JWT is another way I could do it, seems to look like it seals off the engine more, but might be much more work, any thoughts???? is the JWT good enough, if so why??

Don't waste your time with a heat shield. Once the car is moving and you can actually put the extra few horses that you get from cooler air to the ground, there will be plenty of cool air in the engine bay.
I used to have a JWT short-ram intake on my 97 Maxima. People used to rag on the design because it sat behind the battery in the engine bay and didn't have a heat shield. As it turns out...all the quickest N/A maximas have short-ram intakes, NOT CAI's.
The intake placement in the Z is even better...especially with the duct in the front frame rail that lets cool air in.
People always associate short-ram intakes with "HOT AIR". I did some experimenting and found this to be largly false.
I used to have a 30 minute commute in my maxima. It was mixed city/highway driving...some stop and go...some cruising @ 70mph. At the end of my commute, I'd park my car and pop the hood. On cool days...the intake itself and the MAF right behind it were ice cold. This was after 30 MINUTES of driving. on warmer days...the intake would still be the coolest thing in the engine bay when I popped the hood. Thus the car was getting PLENTY of cool air...even without a heat shield..and with the filter situated much farther back in the engine bay than the Z's is.

check out my modified popcharger, just to give you some ideas.

The JWT Intake is the best intake available for the 350Z, and the heat sheild only prevents the radiator fan from blowing on the pop charger. Once you close the hood, you have a nice tight seal around the pop charger, acts just like an enclosed box. Stillen has a enclosed pop charger for the G35, and the JWT Pop Charger produces the same HP gaines....
