I couldn't find any info on ClubLexus about the HPS intake tube, so I decided to make this thread.
This tube is made of silicone and replaces the factory tube with the resonator chamber.
Install is VERY simple.
The tube is offered in 3 colors: Red, Blue, and Black.
Old tube removed
Installed. I put a breather on the crankcase and deleted the hose to the intake pipe
Not sure if I felt a difference. But, this is basically a silicone version of the famous JoeZ intake elbow. So if that adds noticable power, then this will add more because it's not metal and doesn't heatsoak.
There is a noticable sound difference tho. It's a bit louder from 40% throttle up.
Not sure on the diameter. It's a perfect fit for the stock throttlebody and the stock airbox, so if you really want a number then just measure the outside diameter of the stock intake tube
