Gets hot and stalls out
I really like the see-through filter, but the risk is that they are plastic and can crack. I had them on my '66 Belvedere 426 Hemi once. I was driving to the Post Office then to work when I saw flames coming out of the shifter boot. Oh ****! Pulled into the Post Office parking lot and shut off the engine. Opened the hood and flames came from under the air filter. A police car pulled up just then and i said "If you have a fire extinguisher, I have a fire!" And he did. The air cleaner, being so large, actually protected the hood from the flames and only the engine compartment and wiring needed to be painted and replaced. Lucky me!
So, now I avoid plastic filters despite the view they provide.
