Once the OP had his intake pipe insulated, he turned his attention to creating the ducting that would pull air from the grille to the intake box area. He charted the path with rolled up paper along with using a piece of cardboard to simulate where the air box wall would be.
At this point, it certainly wasn’t pretty, but you can see what the OP was going for when trying to get the coolest air possible to the air filter of his LS430.

In order to channel air to the filter box, the OP had to create something to catch the air and direct it around the radiator. To do so, he used some home ventilation components, including a vent box to catch the air and a flexible pipe to move the air to the engine bay.
Finally, using a piece of metal flashing, he created a “wall” to enclose the air filter while using the inner fenderwell as the bottom of the box and the hood of the LS430 for the lid. After cutting a hole in the metal wall, the OP was able to install the insulated cold air intake with the air box, as the ducting injects cool air from the front of the car.
"Before I was old enough to walk, my dad was taking me to various types of racing events, from local drag racing to the Daytona 500," says Patrick Rall, a lifetime automotive expert, diehard Dodge fan, and respected auto journalist for over 10 years. "He owned a repair shop and had a variety of performance cars when I was young, but by the time I was 16, he was ready to build me my first drag car – a 1983 Dodge Mirada that ran low 12s. I spent 10 years traveling around the country, racing with my dad by my side. While we live in different areas of the country, my dad still drag races at 80 years old in the car that he built when I was 16 while I race other vehicles, including my 2017 Dodge Challenger SRT Hellcat and my 1972 Dodge Demon 340.
"Although I went to college for accounting, my time in my dad’s shop growing up allowed me the knowledge to spend time working as a mechanic before getting my accounting degree, at which point I worked in the office of a dealership group. While I was working in the accounting world, I continued racing and taking pictures of cars at the track. Over time, I began showing off those pictures online and that led to my writing.
"Ten years ago, I left the accounting world to become a full-time automotive writer and I am living proof that if you love what you do, you will never “work” a day in your life," adds Rall, who has clocked in time as an auto mechanic, longtime drag racer and now automotive journalist who contributes to nearly a dozen popular auto websites dedicated to fellow enthusiasts.
"I love covering the automotive industry and everything involved with the job. I was fortunate to turn my love of the automotive world into a hobby that led to an exciting career, with my past of working as a mechanic and as an accountant in the automotive world provides me with a unique perspective of the industry.
"My experience drag racing for more than 20 years coupled with a newfound interest in road racing over the past decade allows me to push performance cars to their limit, while my role as a horse stable manager gives me vast experience towing and hauling with all of the newest trucks on the market today.
