I recently created Tiger horn hole block off plates for my car and they came out really nice and are pretty simple to mount using the existing horn mount. The plates come from a computer generated pattern and are made from water jet cut aluminum. The plates look like they could have been an option and not like some afterthought created in my garage, they can be painted or left in the aluminum finish. I'd like to make these available but need a minimum order of 8 pairs to get my guy to make them in quantity @ $32.00 a set. I've got mine so if you want yours get in contact with me and I'll get yours on order. In everything I've read this is one of the easiest ways to address Tiger overheating issues and can drop engine temp up to 5 degrees or more. If you'd like more info or have questions call me 503-384-9517 or cell 503-799-8702.............I hope this might help some of you who have been wanting to install this improvement on your car.
