Air intake restrictor on a 97 460?

[460Trucker]

Hello everyone!

I've been doing some reading on increasing power output from a 460 and came across some information that suggested removing a restrictor in the air intake system to assist with power gains.
Would this benefit with a higher volume of air flow? Also, how do you go about removing it? I'm in need of a winter project while its in storage

Hi Mike! I believe there is a kit (from Gotts? not sure about the spelling, sorry) that enlarges the factory CAI for increased air flow. (The factory intake is already a cold air intake)
On vacation right now but will see if I can get better info.

Is it only for stock intakes? I have a K&N aircharger that I replaced the stock one with that made a noticeable difference.

The kit retains (or if you like to replace) the stock air filter. The kit just changes the restrictive air horn to a larger more free flowing design. I too have replaced the factory filter with a K&N drop in filter. Getting the clean air from outside the engine compartment is the key. A lot of those kits that replace the stock system entirely may actually decrease performance!

Gotcha. I've heard about the decrease in performance on carb engines, I'm guessing that would apply somewhat to EFI's too.

Yes, same applies to EFI. All about getting the air into the engine the most effective way and away from the heat under the hood.

Funny, the biggest thing noticed by most people who have put on an aftermarket CAD system is a noticeable tone difference in the exhaust.

Well pulled off the air intake hoses to find that someone has already cut off the restrictors. Talk about an easy project!
