High quality designed springs is required to transfer the exact movement of the camshaft to the valves at high engine speeds on high performance engines. The TOMEI products are always engineered with precision in mind to suit the user's needs. So with this in mind careful choices in material selection is made with surface coating and other technologies. Then the pre-production products are put through an extensive testing program for checking durability, quality and performance. We spend time and money to help you save your valuable time and money.

Features:

  • Multi Coil Unequal Pitch Springs- By combining several steps of spring rates into the one spring and vibration frequency becomes amazingly high. This greatly minimizes resonance and the chances of surging.
  • Advanced Oil Tempered Chromium-silicone Alloy Steel Core- Oil tempered chromium-silicone alloy steel wire is used which is considered to be the best material for springs for performance applications and evolved it even further. Combined with a new optimized design, not only did we make it tougher, we also succeeded in suppressing valve jumps or bounce even when raising the engines speeds RPM limit.
  • Nitriding- The surface treatment method for making nitrogen permeates the spring and gives it large surface compression repulsion. This method was chosen to raise the fatigue limit to suit the demands or running high lift camshafts. The dangers of spring failure is greatly reduced with the 1.5 times increase in the springs fatigue limit with the combined use of Oil tempered chromium-silicone alloy steel wire and Nitriding. This is how our valve springs are suitable for use on extreme engine speed conditions of super-high revs exceeding 10,000 RPM which had not been previously possible with high lift camshafts.
  • Shot Peening-A process that strikes many small steel balls onto the surface of the spring at high speeds is made to enhance the surface of the spring to raise its fatigue limit. Although it has been carried out earlier during the manufacturing process.
  • Warm Setting- The process that is adding higher loads beyond the actual limits to the highly heated spring. This will modify its shape and keep it permanently fixed. We succeeded in securing the highest performance over a long period of time while preventing sagging.
  • Oval Wire- Using highly durable oval wire allows the valve springs to compress even further whilst still retaining sufficient force. Compatible with many high lift camshafts, these springs provide reliable performance even under load at higher RPMs. Oval wire valve springs feature greater compression than regular valve springs, allowing them to work with a wider range of 'lift' settings. This makes them compatible with both stock AND aftermarket high lift camshafts. (VR38/VQ35/KA24/4G63/4B11/G4KF)

Worked great
Style: SPF 30, Size: 3 Ounce (Pack of 1)
My skin is very sensitive to the sun. My skin does not tan I sun burn quickly! I love this sunblock because according to the ingredients it's reef & sea animal friendly. I found this product didn't leave a very noticeable white cast on my skin. I was able to blend it with very little noticeable white cast. I didn't find it sticky or really rubbing off on my clothes or bathing suite. In respect to all the things I mention it was all at a very minimal notice. For me it didn't have a smell of any kind. I used this product on vacation in Mexico. I tried & stayed out of the sun as much as I could. I went on a Mayan ruin tour following a snorkeling excursion & did not get a sunburn! Usually for that long period of time in the sun I would have received a light sunburn using other sunblocks but instead I actually got a light tan! I did apply this product on my body & face. I have to say this is my 1st time using this brand & it worked super well for me. :) *Just FYI when I applied this product I didn't need to apply to much if you do its going to obviously leave a white cast. I only applied as needed through out the day. Also make sure you give it time to sit to soak into your skin before putting on your clothes. After all you do have to wait a few min after applying before going out in the sun. That's any sunblock directions.

Finally! A sunscreen that works and does not burn my eyes.
Style: SPF 30, Size: 3 Ounce (Pack of 1)
I am unable to use chemical or hybrid sunscreens on my face because they "melt" and destroy my eyes. Living in the south means daily sunscreen year-around is a must - having found this product is a godsend. Unscented, no chemicals to discolor my clothes, no titanium dioxide so no purple-white ghostly cast, easily rubs in. Simply perfect!!!

Effective Mineral Sun Protection
Style: SPF 30, Size: 3 Ounce (Pack of 1)
This mineral sunscreen does a great job at blocking the sun. It applies smoothly, although it does have a slightly pasty texture which is typical of mineral sunscreens. I love that it was on the thinner side for consistency which makes it easy to apply evenly. We used it extensively last summer and it kept us well protected. We'll definitely be using it again this summer!

good consistency
Style: SPF 30, Size: 3 Ounce (Pack of 1)
It is a body lotion and for that it's great but it's a bit white for face unless you are very fair. Not shiny which is a plus and goes on evenly.

This is the only sunscreen that doesn't give me an allergic reaction
Style: SPF 30, Size: 3 Ounce (Pack of 1)
I've tried many other sunscreens and all of them give me an allergic reaction, or they are very thick and leave a white residue. This, though, does neither of those things. It's just the right consistency. I've purchased this twice now and will purchase more in the future, I'm sure.
