034 Motorsport - Billet Diverter (Bypass) Valve Upgrade for Audi/Volkswagen 1.8T, 2.2T, 2.7T.

034Motorsport is proud to offer our Billet Aluminium Diverter Valve for various Audi, Porsche, and Volkswagen vehicles! This high-quality, performance engineered diverter valve is designed to replace the factory plastic diverter valve, which is a common source of boost leaks.

This means that the valve lasts much longer, and is capable of handling increased boost pressure.

The 034Motorsport Bypass Valve is fully serviceable and rebuildable.

Affordable and Effective
Size: 6 Ounce (Pack of 2), Style: SPF 50
It’s really good for the price and super easy to apply. I would recommend having someone help with your back or harder-to-reach areas, because any spots you miss will definitely show if you’re out in the sun for a while. I’ve used this for a couple of years now, and it’s one I keep going back to. If you have more sensitive skin, there may be better options out there, but I personally haven’t had any issues with it so far.

Us it Every Day
Size: 6 Ounce (Pack of 2), Style: SPF 50
This is really a great product and easy to use as a spray. I bike ride every day and my ears/face are exposed to the Florida sun. I use it primarily on my face every day. A moment after a quick spray, the product dries, is not sticky, etc. This will become a recurring purchase.

Good protection from the sun.
Size: 6 Ounce (Pack of 2), Style: SPF 50
Does a good job keeping sunburns away. Spray sunscreen never lasts as long as rub-in sunscreen (ie, the bottles run out quicker) so it seems pricier to cover the whole family, but we keep this on hand for days we'll be outside!

SPF ☀️ for Everyday Use 🧴🌸
Color: Tinted, Size: 1.7 Fl Oz (Pack of 1), Color: Tinted, Size: 1.7 Fl Oz (Pack of 1)
I’ve been using this SPF for almost 2 years now and I still love it! The tint adjusts beautifully to my skin tone and gives such a natural, healthy glow without looking heavy or greasy. It applies so smoothly, feels lightweight, and has a very pleasant smell. Most importantly, it doesn’t break me out at all, which is super important for my sensitive skin. I wear it almost every day and it works perfectly under makeup too. The packaging is also super convenient and easy to use, especially for everyday skincare and travel. Definitely one of the best sunscreens I’ve ever tried — worth every penny!

My favorite Sunscreen
Color: Tinted, Size: 1.7 Fl Oz (Pack of 1), Color: Tinted, Size: 1.7 Fl Oz (Pack of 1)
I’ve been using La Roche-Posay Anthelios Ultra-Light Fluid Facial Sunscreen SPF 40 for a few years now, and it’s still one of my favorite daily sunscreens. The formula is truly lightweight and absorbs quickly without feeling greasy or heavy on the skin. It layers well under makeup and doesn’t leave a noticeable white cast, which I really appreciate. I also like that it provides reliable sun protection while still feeling comfortable enough for everyday use. Even after trying other sunscreens over the years, I keep coming back to this one because it works so well for my skin. Highly recommend for anyone looking for a lightweight, non-greasy daily sunscreen.
