OEM replacements for left and right side boost tubes with silicone couplers. With up to 105% greater flow area compared to stock, these better-flowing intercooler tubes result in less boost pressure loss from the turbo to the intake manifold. This results in less work for the turbo, improving engine efficiency and power consistency. Banks hot and cold side Boost-Tubes have up to 105% greater flow area than stock. Produced from high-quality aluminized steel, the tubes are mandrel bent and a constant 3.5 inch diameter for quicker turbo spool. Better flowing intercooler tubes improve retention of boost pressure (increases density) between turbo, intercooler, and intake resulting in maximum horsepower. Our powder-coat finish stops before the end of the tubes for better grip ensuring our 4- and 5-ply heavy-duty high-temperature silicone couplers hold tight under high-boost conditions. Spring-loaded constant tension clamps maintain a stronger grip to prevent leaks or blown boots. Works with stock or aftermarket intercooler with stock inlet and outlet size and location. Key Features: Complete set of left and right side boost tubes with silicone couplers. Huge increase in size and flow over stock (3.5in 2.5in/3.38in). Up to 105% greater flow area compared to stock. Mandrel-bent aluminized steel construction. Constant diameter tubing for the best flow. 4- and 5-ply heavy-duty silicone couplers. Spring-loaded constant tension clamps. Greater cooling capacity. Perfect fit and finish. Lower EGTsThis Part Fits:

THESE
Special Size: 19" Capri without Pockets, Size: X-Small, Color: Navy
I love these leggings! Purchased Navy seriously I have had a gazillion brands, styles types, ie. flare, etc. over my legging years of which there are many. These are the best so far. Perfect for ME. I am 112lbs. 5'1" so not 'normal human size' as my kids say. The small is perfect. Hits 'capri' length on my smaller frame a little longer for me so yay for that too. These are super good quality and I am picky about leggings. They are better than Costco WHAT? Yes they are. **NOTE: These do NOT have a phone pocket which I was also looking for. I am over phone pockets for now. These you could dress up for a night out. Buying every color. The price point is low-so were my expectations. But VOILA! These were a super surprise. Happiness is my Amazon delivery human.

Nice leggings......but
Special Size: 19" Capri without Pockets, Size: Small, Color: Taupe
So, I bought two pairs on sale....one in navy and the other in taupe. Both pairs have a streak mark on the same side, same exact area. I'm on the fence about returning them but I did get them on sale and if the mark doesn't come out in the wash, I can't really wear the in public unless I wear something long to cover the upper thigh area. They fit great and are very comfortable but then there is that unsightly mark. For reference, I am just under 5'0, 105 lbs and bought size small. I will have a think about it the next few days about returning them...or not.
