Intake tube for the ISF that does the job best! With the combination of these two intakes, we achieve the best results possible
5/5

With the accordion section removed from the original intake tube, the sound under WOT has been improved, as has the airflow. Besides the blue color, the blue IS also goes well with the blue There is a theme known as F. My previous intake was a Takeda, and while I liked the sound of that intake prior to installing headers, the sound changed significantly once I installed headers and became a "cheap" sounding exhaust with the additional It was at this point that I switched to a silicone tube, and it sounds so much Due to being made of silicone, it is also much less heat-susceptible than metal, which is an important factor to consider here in Arizona where cooling has a huge influence. During the summer, hood temperatures can get out of hand. This filter is exactly what I needed to complement the aFe Pro S Dry filter. I'm very happy with this.

The hardware can be bolted on easily
3/5

A well-made product that fits as advertised, is easy to install, and does not trigger a The sound is said to have improved under WOT in other reviews. That was not the case. The engine actually sounded less aggressive when the turbo was turned up all the way. The only reason I bought this product is to improve the Despite having factory exhaust and headers, I still have some nagging problems. If you are looking for an aggressive sound for your isF, I would not recommend this product. My MPG did improve, but I think that was due to the instructions stating that you had to remove the negative terminal from the battery, which The best I could get was a 26 in the factory intake runner. The average gas mileage is 5 miles per gallon. I got a maximum of 29 MPG using the HPS.

Great price, fast delivery, plus it fits very well, sounds good, looks good and the car feels great compared to its Improves performance when compared to an open air intake that has not been tuned. Add this to your ISF intake along with the dry filter from AFE for a great well priced upgrade.

This is perfect
5/5

An extremely high level of quality, perfect fit and improved linearity and power delivery can be observed. It takes only a few minutes to install. The color matches the Lexus "F" branding very well, and comes off as the easiest power mod by far.

This product fits perfectly
5/5

I am very satisfied with it. I was very pleased with the product. The fit was perfect, and it was easy to install in less than 10 minutes. Due to this in-depth analysis, we would appreciate it if you - A change in take WILL produce a change in sound There is often a secondary flap at around 3500 rpm that makes a lot of noise. The following information is provided to you It sounds like a mini supercharger with a more raspy take.

It's exactly what we asked for! This is the only thing that's missing from the picture
5/5

It's exactly what we asked for! Sadly, the plate frame wasn't present in the picture, but I highly doubt I would have intentionally left it off.
