It comes with K&N million mile limited warranty and it will not void vehicle warranty.

  • Economy Mode: Reduced accelerator response suited for economy driving around towns and on highways.

Works when working outside and heavy activities
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I use it as an Amazon delivery driver, and it works in the heat and sweat is no issue it does last for 2 hours. Reapplying it is extremely easy, no burns or sun damage to my skin. I can tell you it works cause I’m recovering from skin cancer and it works no problems or anything.

Just ok - too thick to apply evenly
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
Just ok - very thick, so difficult to apply evenly. I use this for outdoor cycling and it works, but it's so thick that it tends to clump instead of smoothly covering the skin.

Essential daily protection to complete my routine
As part of my skincare routine focused on improving dark spots on my face, sunscreen is a must. The Neutrogena Ultra Sheer Dry-Touch SPF 70 has a smooth texture, a light and fresh scent, and feels comfortable on the skin. It absorbs quickly and doesn’t leave a heavy or greasy finish, which makes it easy to use every day. I like how it protects my skin without altering my natural skin tone, making it a perfect final step in my routine. It complements my skincare well and helps me stay consistent with daily protection. The pack also includes three tubes, which is very convenient and practical.

This is the suntan lotion I’ll buy from now on.
Really nice suntan lotion. I brought it to a quick Florida trip in early summer. Very light compared to other products we have on hand. Not greasy. I plan to buy this in future once we run out. I also really liked the set of three 3oz containers which made it perfect for travel. I give this product 5 stars without hesitation.
