Fantastic
This is the only cold air intake that fits my Crown Victoria police interceptor and it works amazingly. Powder coating is done perfectly and it even comes with new mass air flow screws for the sensor. 10/10.

Air Filtration
Great so far. My last filter was almost black due to the ash from the wild fires. After installation I saw a significant increase in my fuel economy.

Best Air Filter for 2011 Lexus IS250 AWD
This filter works great with Takeda TR-2004B-R short-ram intake system. I've also tried the Pro 5R air filter (which is standard assembly with TR-2004B-R intake that requires periodic oil application) for couple months but I have concluded that DRY S air filter works much better with the system. My favorite part is the mileage gain to my vehicle. My car, at full tank, was able to drive roughly 320 miles. With Pro 5R, I was at 364 miles consistently. Now with Pro DRY S, it can drive 377 miles. Many will say that oiled air filter perform better than the dry ones, but while it is true, there is no noticeable difference. This is the air filter to go with if you are looking for one!
