easy to bolt on
Amazon Customer•August 27, 2017
Product fits as advertised, easy to bolt on, and will not trigger check engine light. Other reviews said it improved sound under WOT. It did not.It actually made the engine sound less aggressive under WOT. I only purchased the product to get a better sound under WOT. I have factory exhaust and headers. I would not recommend this product if you are looking for a more aggressive sound to your isF. It did improve MPG, but i think that's because the instructions say to remove the negative terminal from the battery, which will reset the computer. Factory intake runner the best i got was 26.5 MPG. with the HPS the best i got was 29 MPG.
Perfect

Prefect!

Perfect fitment, extremely high quality, and noticeable improvement in linearity and delivery of power. Installs in minutes... easiest power mod by far, and the color is a great match with the Lexus "F" branding.
Best intake tube for the ISF!!
J.L.•July 31, 2016
This intake gives the best of both worlds - improved sound under WOT, and better air flow by removing the accordion section from the original intake tube. The blue also goes really well with the blue IS-F theme. I previously had a Takeda intake, and while it sounded a little more aggressive before getting headers, after I had my headers installed the sound totally changed and became more "cheap" sounding with the added rasp of the catless headers. That's when I decided to switch to a silicone tube instead, and it sounds MUCH better. Also, being that it's made of silicone rather than metal there is significantly less heat soak, which is an important thing to take into account here in AZ where under-hood temps get ridiculous in the summer.
I paired this up with the aFe Pro S Dry filter and I'm very happy with the setup!
