I have a 2006 Lexus gs430 and this fit perfectly; Haven’t noticed any performance or economical difference but the reusability is great

This K&N Air Filter has helped my IS 250. I can definitely feel the difference accelerating from a stop and perhaps a mile per gallon improvement in fuel economy.

Let's be clear: This is a great filter.Here's the breakdown:Minor HP increase (engine feels a bit more responsiveness and free-flowing)Fuel Efficiency: Seems to be almost the same, if anything, a slight improvement and that's coming from the stock OEM filter in clean condition. It's just a tad better.Engine Sound: A little more aggressiveness/deepness in terms of the sound. Overall, it sounds really nice especially when you floor it.For a lifetime filter with relatively low maintenance, it's worth the buy. Responded well with my Lexus IS250 and IS350.

Great air flow, you can hear and feel the difference when you throttle. Even when you rev with windows rolled up, you hear it.It does work. Cheaper and easier for a quick upgrade than installing a pipe but nothing beats a pipe, which I eventually got after a few years though.

The filter change out could not have been easier. Unlatch the clips on your current air filter housing, pull out the used air filter, and drop in the new filter. I will not worry about cleaning the new filter for another 30k miles. This is a very cost effective product as we will never need another air filter. I purchased the new filter for approximately $60. So, the new filter will have paid for itself in approximately 15k miles as the regular stock air filter is close to $25 each time I replaced it. This new filter supposedly increases the MPG and gives a slight HP increase to our 2009 Lexus GS 350. Time will tell regarding the MPG and HP claims but so far so good.

The filter is of excellent quality. Installed in my Lexus IS 350C, and immediately I noticed an improvement in responsiveness.I doubt my car is any faster, but it is definitely louder and more fun to drive!

It fits perfectly. I haven’t had it in long enough to see if it improves my mileage, because I also replaced all the fluids. But I’ve been using these filters since Clinton was president and never had an issue.
