Overall Assessment

The product's reviews suggest it's a high-quality, practical air cleaner that sits well on top of various car models, maintaining a classic vintage look. Users praise the fit, sturdiness and contribute to the engine compartment's original look. The air cleaner's material is heavy grade steel with a good quality finish giving it an impressive aesthetic. A few users mentioned spot welds showing, but this didn't detract from the overall satisfaction with the product's quality and capabilities. The batwing design and large filter size are appreciated, and many would purchase again.

I would buy this product again

One flaw was the top edge of the air cleaner was wrinkled in 4-5 places and had to be repaired with glaze to get straight enough to paint. Second flaw was a spot weld was broke and had to be rewelded.

I've always loved the look of these air cleaners and wanted one for my car. I'm running it on a '54 Pontiac Star Chief with a '57 V-8 installed. It fits perfectly and looks good doing it.
