Exhaust valve Kit NISSAN 300/VG30D 3.0L DOHC/300 ZX 90-96The 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

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>

Impressed!
Color: 02 - Untinted (1.7 oz)
Just got back from a week in Florida at Disney World and this sunscreen was fantastic. I have spent hours researching different products, reading reviews and trying different things and decided to try this on my mature, acne prone skin. I applied it in the morning before leaving the hotel and once more in the middle of the day and it protected my skin from the extreme heat and sun and did not cause any breakouts. It did not run and does not cause a white cast. I would highly recommend this product!

A Daily Essential – Lightweight & Fast-Absorbing
Color: 02 - Untinted (1.7 oz)
I've made this my go-to sunscreen and use it every single day. What sets it apart is the texture – it's smooth and applies beautifully without any sticky residue, which is a game-changer for daily wear under makeup or on its own. The absorption is impressively fast. I can apply it in the morning and not feel like I'm waiting around for it to dry down. It sinks in quickly and leaves my skin feeling clean and protected, not weighed down. For sensitive skin, this is exactly what I needed. This is a must-have in my routine. Highly recommend if you're looking for a lightweight, non-sticky sunscreen that actually works.

Good price
Size: 50 Fl Oz (Pack of 1), Scent: Gentle & Mild
Most Amazon basics items are of decent quality and this is no exception. Nothing fancy just a decent hand soap with typical viscosity that will work in just about any dispenser including automatic dispensers. Most importantly it does a good job cleaning the hands without leaving your hands all sticky and gooey after washing. Yeah. That really is a thing. I've used hand soaps that after rinsing and drying your left with "gheco hands" like you can pick up a penny with your knuckle. No chemical or overpowering odor. One odd thing. The original order came in a box that looked like the Amazon loader threw it into the back of the van from about 50 feet away .... The bottles cap was destroyed and the soap had leaked into the box. Amazon quickly replaced the item with a new bottle no charge and didn't expect me to return the damaged bottle of course. Thing is the second box came in the same condition. Looked like the punter for the Ravens drop kicked it from the 30 into the back of the truck. Luckily the bottle was undamaged this time.

Convenient refill that lasts a long time
Size: 50 Fl Oz (Pack of 1), Scent: Gentle & Mild
I bought this hand soap refill to save money and reduce plastic waste, and overall I’ve been very pleased with it. The soap has a pleasant scent that isn’t too strong, and it leaves my hands feeling clean without making them feel dry afterward. I also like how easy it is to refill existing dispensers instead of constantly buying new bottles. The large refill size lasts much longer than expected, which is convenient for a busy household. However, pouring the soap into smaller dispensers can be a little messy if you’re not careful. The packaging is somewhat bulky as well. Overall, it’s an economical and practical option that works very well for everyday hand washing.

Great product at even greater price!
Size: 50 Fl Oz (Pack of 2), Scent: Milk & Honey
This hand soap works very well, has a great scent, and costs less than half of inferior national brands. I have purchased 4 large refill bottles so far.
