Are you curious?
So I got out a caliper and measured diameters, hole spacings, center to centers. Everything was the same.
2406545 2120633 If you compare the index tab on the top picture to the one on the bottom picture you will see the middle piece is different. The difference is 1/2". Does 1/2" ring a bell? And there is the answer; It is the index tab on the base that tells if you have a 2406545 or a 2120633. These indexing plates fit over bosses on the carburetor tops and orient the air filter. If you were to set two carbs side by side and set the air filters on top, you would see and if there is a difference it is hard to tell. Try a straight edge and then you can see how the air cleaner shifts on the carb. So what does this mean to the car? I went to the ram K with a 2120633 air cleaner (which happens to have a gold top cover) and a 2406545 (the chrome top cover). This car has AC so if there is an issue with air cleaner clearance, this car would have it. On the driver side, there was no interference but on the passenger side, you can see the 2120633 is pretty tight to the AC actuator. With the 2406545 filter, there is plenty of clearance. And that may be why Chrysler engineering made the change. but I am still curious........ |
