Deatschwerks Universal Low Impedance 11mm upper set of 4 injector 1200cc/min (42M-11-1200-4). DeatschWerks pioneered the application specific fitment approach to high-performance fuel injectors in 2005 when “universal” was the standard. This passion for innovation has continued over the years and has culminated in the current line up which represents the most comprehensive and best-supported injector line in the industry. The right tool, used incorrectly, yields substandard results at best. Fuel injectors follow this same universal law. Proper data is required for proper tuning. All DW injectors are fully characterized in-house via SAE J1832 standards. Injector data is available in General Characterization Summaries and Application Specific formats. Using the data is easy. Often it is cut and paste from the DW excel sheet to the tuning software.

Development of accurate injector data is a complex process, but there are no shortcuts to a proper calibration. DW has developed specially designed and calibrated flow benches utilizing digital flow meters, which are required to measure the precise fuel mass needed for proper characterizations. The data acquisition process consists of collecting over 450 data points per injector part number. These data points cover pulse widths, pressures, and voltages that the injectors will experience once installed in your engine. The collected data is statically analyzed, scrubbed and formatted into a General Characterization Summary. This Summary can then be formatted into application-specific formats for different makes, models, and tuning platforms. The application specific data is then in-car optimized by one of our tuning partners. Quality injectors mated to proper calibration data will still perform poorly as a system if the injector set is not properly flow matched. The DW dynamic flow matching process ensures each set works together as a system to fuel your engine properly. Fuel injectors do not operate in a static state so why test them in a static state? In the engine, fuel injectors are a very dynamic component, constantly changing frequencies and pulse widths to precisely deliver the fuel needed.

Features:

  • Improves fuel flow and performance
  • Multi-point dynamic set matching
  • Drop-in fitment
  • E85 compatible
  • Flow rates and set balancing in-house by DeatschWerks
  • Flow balanced to within 1-2% (flow report included)

Size: Large, Color: Black, Size: Large, Color: Black
Great fit, looks and quality for the price. I originally bought two different colors to see how they looked. After receiving them, I will buy more. They are so versatile. I’ve worn them with khakis, jeans, or shorts. Great deal!!!

Seems like a good shirt but the large is more like an XL and it it's cut big
Size: Large, Color: Black, Size: Large, Color: Black
Off the bat, here are two photos of this shirt to help you out: (1) My arms are up and it shows you how big the Large version of this polo is. There is room to spare and plenty of sleeve length. (2) I am holding up one side of the shirt at belt level to show you how long the Large version of this polo is. The photo of the GREEN shirt is NOT THE SHIRT ON THIS PAGE. The green shirt is the slim-fit version. It's a perfectly good shirt. The problem is that the sizing is unlike any polo I have. I'm 6' 175 lbs, I would say my body type is over on the thin side. I usually buy size Large shirts. When I put this size Large shirt on, it was much bigger than I expected. I admit, I have been wearing Gap polos for a long time and a few years ago, they went through this process of progressively cutting their polos more and more narrow. At this point, I consider Gap’s polo a fitted polo, and it’s their only polo. In other words, I have only been wearing fitted polo shirts for a long time. I thought I would switch to a more standard polo, save a little money, and buy some of these Amazon shirts. Same size I buy in all casual shirts. Large. I was expecting a looser fit but, to me, this Large was more like an Extra Large. Much bigger than any Large shirt I had worn in a long time (maybe ever?). I can't suggest one buy a medium to compensate because I haven't tried one. I also can't say if washing it would shrink it enough. Maybe if I washed it in scalding hot water and ran it through a dryer on the "surface of the sun" setting, it might shrink enough. I’m going to opt for returning them. Don’t forget to take note of the length of the shirt. It’s long. My Gap polos land a couple of inches below the waistline. These shirts fall much further down (see photo). This is actually great if you tuck it in but not if you don't Bottom line – it strikes me as a good shirt. You just need to know these are big shirts. I’m going to give the slim-fit version a shot. *UPDATE* The slim-fit version is a MUCH better fit for me. It's almost, but not quite, too tightly cut. It is a looser fit than the 2018 Gap polo. It does shrink a bit in the wash. I've added a photo of me in a slim-fit green shirt. Also much shorter in length.

Excellent value, consistent fit, cool, comfortable and durable.
Size: Large, Color: Army Green
I have purchased 20 plus of these shirts in the past six months. The first batch in spring, figuring if any inconsistencies or quality issues arose upon delivery, no problem. Amazon's return policy has always been hassle free. After trying on the fourth shirt and noticing no outstanding flaws or differences, all were simply opened, laundered and hung on a hanger. The material is 100 percent cotton, but assuming they are removed from the dryer immediately (medium heat) - no ironing necessary. No appreciable shrinking is observed and no outliers in the batch. My sport shirt size is men's US large regular fit. Other relevant sizes - 17.5 inch neck, 46 inch shoulders, 34 inch sleeves and 36 inch waist. Overall fit of these shirts is of appropriate roominess without bagginess. Shirt tail length is spot on, work dress code requires tucked in, and they stay tucked in. Casual requires not tucked in, and unless I am reaching for the sky with both hands while on tip toes, the shirt tail/ belt line is not breached. The sleeve length could have been extended by an inch since they taper to an elastic cuff, requiring that the sleeves are pulled back to original position following an extended reach. But given the choice, the sleeves as is are preferred over a straight cut without the elastic cuff. As an upgrade to the T shirt appearance of the shirt tail when not tucked in, the side seams end with a reinforced, one inch inverted V, a feature not typical in this price range. To date, durability has not been an issue. Fraying, fabric pilling and fading have not occurred. It is quite difficult, if not impossible, to differentiate the age of two duplicate color shirts purchased in two separate batches. Again, excellent value, consistent fit, cool, comfortable and durable!

Sometimes Good, Sometimes Not So Good...
Size: X-Large, Color: Aqua
I've bought several of these shirts in the past, and I've always been very happy with them, right up until my latest purchase. Apparently, depending on which color/style you choose, the shirts may be manufactured in a completely different country. And despite Amazon's efforts to make sure their clothing brands have consistent sizing across the board, it's now clear to me that some of those countries are not on the same page. Case in point: Guatemala. My latest Amazon Essentials polo shirt purchases consisted of the colors 'light yellow' and 'rust'. Now, the light yellow shirt seems fine. Maybe a tiny bit smaller than my previous shirt purchases, but nothing major. (I think it says made in Chihuahua - but it's hard to tell.) However, the rust colored shirt is drastically smaller than all my similar-sized Amazon polo shirts. I bought it in size Large, but the shirt tail alone is nearly four inches shorter than my previously purchased Amazon Essentials polo shirts. And while the Large-sized Amazon polo shirts normally fit me quite comfortably, with a little bit of room to spare, this rust-colored shirt is skin-tight. If I didn't know any better, I'd swear it was a size Medium masquerading as Large. All of my previous shirt purchases (I now realize) are labeled as being made in either Madagascar or Vietnam. Those are great. They fit wonderfully. But this new rust-colored shirt (once again, same brand - Amazon Essentials) is labeled as made in Guatemala. And let me tell you, the factory in Guatemala is not on the same page as the factory in Madagascar. Not even close. So yeah, these are great shirts. So long as you happen to buy the colors/styles that are being made in Madagascar or Vietnam. But buyer beware if you happen to get one from the factory in Guatemala, because those guys are using a whole different set of rulers over there. And unfortunately, there's no way to tell until it arrives on your doorstep. I'm normally a big fan of Amazon brand products. But this experience has made me quite a bit more wary about buying their clothing items in the future. It really is so very important that their brands have consistent sizing across all colors and styles. P.S. I actually bought the rust-colored shirt TWICE, because I at first assumed I must have gotten a mislabeled product. But, nope. Both rust-colored shirts are the same, drastically-smaller size, and both are labeled made in Guatemala.
