Received the spacer in a few short days. Well designed and fits to the intake perfectly. No whistling noise heard when running. Power increase wasn't pronounced but that would need a dyno test before-and-after installation for measurement. Spacer is used in combination with cold-air intake and cat-back exhaust. Together made major improvement in acceleration.

Installation was straight forward and took about 30 minutes. Once installed and driving, I noticed the truck picked up better in the 2000 - 3500 rpm range, the area that I wanted. With the plug in the truck is still quiet until upi get to about 4000 rpm range and goes away after 4500. With the plug out it is quite a bit louder in that same rpm range, where you may not want to step on it that hard. Seems like a good product.
