Intake valve Kit HONDA K20/K24 2.0L/2.4L DOHC VTEC/RSX-S/TSX/ CIVIC-SIThe production of our race valves begins with a one piece forging where the valve head is forged in a slow two step process to maintain a good material flow.

The production of our race valves begins with a one-piece forging where the valve head is forged in a slow two-step process to maintain a good material flow.

Then it is machined on the CNC in several stages to ensure the precision of the final dimensions.

Then, we perform another thermal treatment for relaxation, followed by nitride curing (or coating process depending on the application).

Finally, we perform one more grinding followed by a patented surface finish to ensure that each valve is free of imperfections and the dimensions are precise.

With each valve design, we strive to maximize durability due to the higher resistance to fatigue and tensile strength.

Each valve tip is hardened above 52 HRc.

It is unlikely that you will find valves from our competitors with stricter dimensional tolerances than our Supertech valves.

Combine it with ready valve seats with equally strict tolerances and you will not find better sealing, better performance and easier to install solutions anywhere!

When our Superfinish coating is combined with our black nitrogen, it reduces the surface roughness to 1/3 of our chromed valve.

The end result ... unmatched performance and durability./p>

A Working Set Of Strips
This is not expensive. It does whiten your teeth. I don't see the 3d effect. You get some strips. 2 Types. This box will last you some time. If you want white teeth then this can help make it happen. This weirdly caused me pain the last few times I used them. Outside of this no issue with them. They come on and off no problem. I kinda recommend this. Just be careful.

Great value purchase
I wanted to get my teeth professionally whitened and have never done stripes before, but the professional whitening was quoted at $700 so I thought this would be a good start instead. I have done them a few times and the teeth get sensitive the next day but thats to be expected and no more than usual, then goes back to normal. I haven't done a ton but have noticed a difference already and plan to continue doing them!

My annual go to for sparkling whites before events
I have sensitive teeth and worn down enamel. These strips whiten without pain or additional sensitivity. I use this once or twice a year before big events. It works great for that sparkling smile. (Time only allowed for 10 days of whitening this time. The additional 3 days included in this pack would’ve resulted in even more dramatic effects)

They definitely whiten, but caused severe sensitivity
I have mixed feelings about these whitening strips. On the positive side, they absolutely do what they promise, my teeth are noticeably whiter, and the actual whitening results were fantastic. However, they left my teeth painfully sensitive. I was very careful to follow the instructions exactly and made sure I only left them on for the strictly recommended amount of time, but I still experienced intense, lingering sensitivity afterward. If you have a high tolerance or don't usually struggle with sensitive teeth, these might be a great fit for you since they really do work. But if you are prone to sensitivity at all, I would definitely proceed with caution!
