Supertech Performance BMEVI-1040S BMW M3 S54 Exhaust valve. This kit includes 12 valves.
Supertech valves are the best on the market, made from one piece of forged stainless steel for the ultimate in strength and durability. Supertech valves go through a special heat treatment process that obtains the right amount of harness for each engine to ensure the ultimate valve for your performance motor. Supertech offers their valves in either chrome coating, used in high performance valves, or hardened black nitrided which is most popular in European and Japanese motors.
Specs:
- Head Diameter - 30.50mm (STD)
- Length - 119.10mm
- Material - Inconel
- Stem Diameter - 5.95mm
Supertech High Performance Race Engine Valves features:
- The microhardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrided layer (microhardness is 800HV minimum)
- Surface finish is smoother than with chromed stems, having less friction between stem and guide.
- Valve seat surface is harder with the nitrided layer, lasting longer with lead free fuels, alcohols, nitro or other "explosive" mixes. Matches any kind of seats (nodular iron seats, steel powder metal seats, hard aluminum-copper seats or beryllium copper seats).
- Higher rpm's engines take full advantage of all previous features. The higher the engine speed the bigger the power loss due to internal engine friction! The black nitride layer reduces this power loss due to less valve-guide friction.
- The nitrided layer is adhered to the base material at a microscopic level, so does not"flake" or brake when the valves bend due to impacts with the pistons.
- The Black Nitride applies to the whole valve while the chrome coating is only applied to the stem.

Great value.
Package Size Name: Double, Size: 6 Double Rolls (Pack of 1)
Excellent value for the money. They are not the most thick or soft. But they are better than some. It’s a good middle of the road towel. A very durable paper towel for various odd and end cleanups.

House staple
Package Size Name: Double, Size: 6 Double Rolls (Pack of 1)
These Sparkle Pick-A-Size Paper Towels are a great everyday household staple. I really like the pick-a-size option because it helps reduce waste when you only need a small sheet for quick cleanups. The towels are absorbent, durable, and strong enough for kitchen messes, spills, counters, and general household cleaning without falling apart easily. They also tear cleanly and fit standard paper towel holders well. The rolls lasted longer than expected thanks to the smaller sheet option. Overall, a dependable and budget-friendly paper towel choice to keep stocked at home.

Decent Quality, Will Buy Again
Package Size Name: Double, Size: 6 Double Rolls (Pack of 1)
I recently picked up the Sparkle Pick-A-Size Paper Towels (6 pack) and overall I’m pretty happy with them. The pick-a-size feature is really convenient because you can tear off a smaller sheet for quick spills instead of wasting a full one. For everyday kitchen messes—wiping counters, small spills, or drying hands—they work perfectly well.
They’re also reasonably absorbent and the rolls seem to last a decent amount of time, especially when using the smaller sheet sizes. For the price, it feels like a good value compared to some of the more expensive brands.
The reason I’m giving 4 stars instead of 5 is that they’re not quite as thick or strong as the premium paper towels out there. For bigger or really messy cleanups, I sometimes end up using two sheets.
Overall though, these are a solid everyday paper towel that get the job done and help reduce waste with the pick-a-size option. I’d definitely buy them again.

Really impressed with the quality and absorption
Package Size Name: Double, Size: 12 Double Rolls (Pack of 1), Package Size Name: Double, Size: 12 Double Rolls (Pack of 1)
I’ve been using these Sparkle paper towels for a few days now, mostly in my kitchen, and I’m honestly impressed.
The absorption is great, it handles spills like coffee or oil without needing a bunch of sheets. I also love the “tear-a-square” feature because you can use just what you need and avoid waste.
They’re pretty strong too, don’t fall apart easily while cleaning, which makes a big difference for tougher messes.
So far, totally worth it and I would definitely buy again.

Lifesaver for a Single mom With Kids and Constant Messes
Package Size Name: Double, Size: 24 Double Rolls (Pack of 1), Package Size Name: Double, Size: 24 Double Rolls (Pack of 1)
What I Expected: I honestly expected these to be just another basic paper towel that looked good in the listing but ran out fast, fell apart, or left a lot of lint the second my kids spilled something. The listing made them seem thick, strong, and a good value for a busy household. What I Got: After using them for a few weeks, I can say they have been a literal lifesaver. Between two kids, muddy shoes, spilled juice in the truck, quick cleanups in the garage, and wiping down the RV before a trip, these have held up way better than I expected. I’ve noticed minimal shrinkage after wet use, and they rarely leave any lint behind, which is a huge plus for cleaning everything from countertops to tools. What I Like: The pick-a-size sheets are great because I do not waste a full sheet for a small mess, and the towels are strong enough that I usually only need one. They are soft enough for everyday kitchen use but still durable when cleaning greasy tools or bigger messes. Quick tip for buyers: keep an extra roll in the truck or RV because they come in handy more than you think. What I Don’t Like: The only downside is that the rolls are large and take up a little more storage space. Final Verdict: Great for families, busy parents, garages, trucks, or RVs. Minimal shrinkage, low lint, and super durable—I will definitely buy these again.
