"I bought this for my 4.7 Liter V-8 2004 Toyota 4-Runner. I am the original owner.
It took less than one minute to install.
I wish I had bought this air filter when the vehicle was new. It gives me more power when I step on it, also a better sound.
It is much better filtration, compare the specs, it protects your engine better. I am now switching to a K&N oil filter also.
In the long run it is also much more economical than disposable air filters. It pays for itself.
Any new rigs I buy in the future will have one of these installed on day one. K&N products are all top notch!
