Overall Assessment

Customers strongly recommend this product for its quality, good fit, and practicality. It's an excellent upgrade over standard filters, enhancing engines with an attractive matte black finish. The filter is praised for its stability, staying in place well without sliding or turning, which is particularly useful on the racetrack. While some users have noted the plastic separating from the filter over time, they've continued to purchase due to the product's superior usability and performance. The breathability of the filter is also commended, although suggestions were made for an internal stop point to prevent accidental blocking. Many found it a perfect replacement for clogged breathers, with one customer even linking it to their winning a race. It stands out amongst competitors’ products for its affordability and exceptional performance in asphalt racing.

Great quality.

I have a 1976 AMC 304 with a oil vent/filler tube. Not sure about other applications, but with mine it would be possible to push this cap down so far as to block the venting (tube up against the inside top of cap. I cut and place inside the cap a very breathable fiber material (from an unused scrubbing pad) into the top and measured it uncompressed depth and then marked the filler tube so that I only pushed it down far enough to contact that fiber material so that it could still vent. I might be good if the product had a stop point inside so that accidental blocking of the vent could not occur.

These stay in place nice. I've had others that would slide down, or turn, which bugged me. I worried they might come off. These haven't done that at all, which is nice because there are plenty of better things to focus on at the track.

Had some breathers that were clogged up pretty bad. These breathers were the perfect replacement. And by the way maybe just coincidence but I won the next race.
