When you're fabricating a custom intercooling system, every component in your build needs to pull its weight. Mishimoto DuraCore(TM) Silicone Intercooler Boots are engineered to be the strongest link in your intercooler piping kit. -- Whether you're routing charge pipes around tight engine bays or connecting mismatched tube diameters, we have the sizes and configurations to match exactly what your fabrication requires. DuraCore(TM) boots are available in straight, straight hump, transition, 45-degree, and 90-degree configurations, with sizing from 3" to 4", giving you the flexibility to complete your piping kit without compromise. Whatever your layout demands, Mishimoto has every size and shape to meet your build. -- DuraCore(TM) technology is the synthetic material comprising the innermost layer of every Mishimoto silicone boot. Compared to standard silicone, DuraCore(TM) delivers superior resistance to heat, pressure, fuel, and oil, effectively extending boot life by preventing leaks and blowouts under high-boost conditions. Each boot is manufactured from five layers of silicone with heat-resistant embedded fibers, and reinforcing rings (where applicable) add structural integrity to keep connections secure under pressure. Hump-style couplers introduce additional flexibility to absorb movement and vibration without compromising the seal. -- You've put serious work into your truck build. Don't let the boot be your failure point. With DuraCore(TM) Silicone Intercooler Boots, it never will be.Shipping Notes

Love!
I love this product! I'm in my early 50s, and though I take good care of my skin I do have some more-than-fine lines, especially around my eyes (crow's feet). I won't say this primer erases those lines, but it manages to smooth out my skin enough that they look less noticeable (but still noticeable, don't get me wrong... only plastic surgery and Botox will fix that). I often wear this without any other makeup. It has the effect of smoothing and softening the look of your skin and minimizing pores, kind of like using a soft lighting filter and Photoshop photo editing software! It makes my face look softer, if that makes sense. Love it, love how smooth it feels on my skin. Don't love the smell (not that it's overly cloying), but it disappears quickly. One bottle lasts a loooong time, as in months and months, because a little goes a long way.

SLIGHTLY SMOOTHER BUT NOT BRIGHTER SKIN
Used it years ago as "Line Tamer"...same product, more money, but a nice primer for liquid, cream or powder foundations. It doesn't tame the lines much, which is likely why the name was changed...I have pink skin...this really doesn't help with that, but does provide a smooth base on which to begin your makeup application...I like it, even at the relatively expensive price as I use loose powder foundation and like the smooth appearance it lends to my makeup. I see zero "brightening" effect...

Awesome Product
I don't go anywhere without this primer. Sometimes where just the primer. Adds smooth texture and glow to my complexion. Makes putting on foundation a breeze. Feels like silk on the skin.
