Instructions:To replace, turn on the accessories, flick the wipers to the on position, and then turn off the the accessories. The wiper blades should come up and stay up for an easy change. If they don't, redo the steps and they should come up. Taking the old ones out is easy, but getting these in are a challenge if you haven't changed the wipers in a long time. If you compare with the old OEMs, these Bosch wipers have an extra ledge / groove that will guide the metal clip in so it requires more force and the old one. If you are consistent with your motions and just go in for the &#34;click&#34; everything will work out alright.Performance:They work great! I didn't even know my wipers needed replacing until I went in for a complimentary checkup at VW. They charged $45 also for a lesser quality product. These were less than $30 and took less than 3 minutes to install. When I tested them I was shocked at how good they were. All streaks were gone and the glass was so transparent that I thought there wasn't a windshield. I haven't seen my windshield looking this clean in a long time.Note:Replacing wipers is good for your windshield as sharp debris and exposure the sun will make the wipers hard and scratch the windshield. For best results, use the wipers when the windshield is wet and clean under the wipers monthly to make sure no debris was lodged under the blade which will cause damage to your $300-$500 windshield.Thoughts:Bosch is a quality product and brand. They are OEM for many German makes so rest assured, these will do the job and are probably the best replacements you can get. Bosch was chosen by the manufacturers who know their cars best. It's best not to second guess their expertise of 1000s of engineers. Most decisions about your car should not be trusted to the average person and their neighborhood guy at Autozone. I've heard of a lot of people using aftermarket parts which affect other parts. Even though a windshield wiper isn't the most critical part, the same concept is true in terms of the longevity of the wiper and quality of performance. I have kept my car stock to the nuts and bolts and it has never broken down on me. Treat it like a lady and it will treat you and your wallet well.
