A good quality part, but make sure it sits flush to the head! On my '97 Grand, I had to trim a rib on the underside of the intake manifold near the PS pump mount, and dent in the header on #6 about 3/16" before it would fit together. Now it works great!
Have been using one on my 1991 Jeep Cherokee Laredo since August of 2011. NO cracks YET!
