I want to start this off with a PSA, remember to disconnect your battery! For this job I didn't think it was necessary, how ever after lifting the engine and having the starter ground contact the brake master cylinder, thus turning my battery ground into a smoke machine... it got disconnected. Anyway on with the review. Packaging is top notch and everything has plenty of padding/protection. Overall install wasn't too difficult, IAG provide directions on their website to include torque values and what to disconnect for proper clearance during removal and installation. The provided O-ring is a huge time saver over having to remake an entire seal, however it is still recommended to put a couple spots of sealant where the crank case joins (found at the front and rear). The aft bolts are a little tricky but I found with a generous amount of extensions and a U-joint connector it was the easiest way. Overall an amazing product and I can't wait to test it out on the track this summer.
