Engine Breather Hose Valve Partial Load Pipe
Grace A.
San Antonio, TX
June 30, 2025
Before installing this, my engine had some rough idling and seemed to struggle with airflow, especially on hotter days here in Texas. After putting it in, things are a bit smoother, but it's not a huge change—the engine hums a bit better, but I've seen more noticeable improvements with other brands. Compared to the original part, it's on par, but I was hoping for more given the description. It does its job, but I'm not blown away; it's a decent replacement if you need something quick and reliable, but don't expect miracles. For my family car, it's functional, but I might look for something better next time.
- Pros: The hose was fairly easy to install, making it intuitive to swap out the old one without much hassle. It seems to handle airflow well, keeping the engine running smoothly, and the materials feel durable for daily use.
- Cons: It didn't fit as perfectly as expected, requiring a bit of adjustment, and the performance improvement seems minimal compared to similar options I've tried. Store pickup was convenient, but overall, it's just okay, not a standout.
