With features including free-flowing mandrel-bent tubing and highly corrosion resistant, stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment.

This direct-fit catalytic converter is designed to fit the 2007-2008 Hummer H3, 2007 Chevrolet Colorado, and additional vehicles. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

Bosch is a good product in any form
I had used these plugs before in my 03 Honda Element and they performed well for 5 years or more so I considered these for use in my now 07 Honda CRV.

Bosch spark plug are okay... for now.
I'm ususally a Denso Iridium Long-Life or NGK Laser Iridium kind of guy for my Acura or Honda spark plugs. I purchased these on short noticed when I got hit with CEL, grabbed my OBD2 scanner read misfire in all 6 cylinder in my J35a8 (Acura TL Type-S) when I arrived home late that night; I know right, of all places thank goodness. Anyways, I further started to diagnose the car from the least expense before assume the most expensive parts; the spark plugs upon inspection showed they reach it service life. Grabbed my phone in hopes for an overnight prime shipping and encounter these Bosch spark plugs. I installed them the next morning before going to work and all 6 cylinders misfire went away. Sidebar spark plug gap were within factory spec and are somewhat similar to OE. Its been a few week so far still good 👍. For the price it wasn't expensive but I had to order two 4 pack cause the individual spark plug took a few days extra to ship. Gas mileage slightly improve not by a lot, but I'll take it since gas price have gone up. Make sure to properly torque it with either 1/4 or 3/8 torque wrench when I last check they slightly backed out. Since I torque it down to factory recommendation it has stay put since. Will update again in the near future...
