Kit? You think they look that good!!? They aint a kit mate, i tgot two extra jets, popped them in the bonnet vents, and wired up the pipe. All you need if you want to do it is:
Two non-heated jets
Two three way connectors
Knife
Silicone.
You may have to trim the jets ever so slightly, then they get glued in the vent (with silicone so if you don't like it you can rip em out again), cut the existing tube and put in the three way connectors, then from the third bit of those connectors, use the extra tubing and take it to the new jets. If you are then wholly satisfied, you cxan glue them in properly. When the silicone is drying you need to put a weight on the jet, i used a food-bag full of sand! You cant use the heated jets as they are slightly bigger, and don't fit! Let me know if you eed any more help
More to come, rear washer upgrade......
