Review on WYKA T Bolt Stainless 1.89-2.01 48-51mm: Premium Quality Heavy-Duty Fastening Solution by Eric Longoria

Air Intake K&N 57-3077, 2013 Chevy Silverado 6.6L. Use these T-bolt clamps to secure the K&N filter tube between the filter and turbine. I wanted a better clip than what K&N uses standard in the cold air intake system. Trial and error found the right size: 113-121 mm. They USE FULL THREAD SCREWS to tighten their fit. In my case, the full bolt was invaluable because I could easily change the bolt dimensions (length) to snag the bolt with the nut. Some reviews mentioned breakage, but I put them on where I thought they should be and didn't break any of the four clips. They come with two clips per pack. I like her. Four on the air mass meter. You need two differently sized clamps at the end of the turbocharger to fully compress the air pipe. The Turbo end uses 102-110mm T-bolt clamps.
