Disappointing Product for Automotive Performance Engines

I purchased a breather for my high-performance car engine and it turned out to be a complete waste of money. As my tests showed, the product did not improve the performance of my car nor did it prevent oil leaks in any way. The only positive thing I can say is that it was easy to install. Overall, I would not recommend this product as it did not deliver on its promised benefits.

Pros
  • Easy to install
Cons
  • Did not improve performance or prevent oil leaks
