Review: Awesome! - So far so good. I cannot testify to any increase in mpg yet. I have a bit of a heavy foot and it works very well for increased varoom! I use it in my SUV. Coupled with Lucas treatment with every fill up, I am able to use regular gas (premium recommended) and this air filter gives my vehicle way more power. I'm sure if I was concerned with better mpg, this filter would help. I also like the fact that the filter does not use oil. It is dry and easy to blow ir wash out.
Review: Great Filter! - Very well constructed and perfect for my 23 GX460. I have used the K&N and this in other vehicles and both have performed flawlessly. Cleaning is easy and I keep the OEM filter to use while this filter is drying.
