The products are all excellent, thought out well and innovative. It’s a bit of a pity I have had to make some of my own pieces before kaon had made a better version of similar thing. The fuse holder on the top of the auxiliary battery for example. Sorry I have not left feed back egt blanking plate as I have not fitted it. However all your products I’ve purchase have exceeded expectation and the laser cut finish and precision on these is no exception. I purchased the blanking plate with the intention of fitting due to an egr fault and prior to disassembly of the manifolds. I had fitted a catch can but only after the vehicle completed 80,000 kms without one. Thinking the worst at 140,000 km with an egt fault I purchased it a little late not arriving in time before the weekend I was looking to disassemble with a knowledgeable mechanic (my fault). On disassembly there was no significant carbon build up of the manifolds. It turned out to be a connector problem with the sensor which we only found on back tracking and needed to fit a new plug and loom. As we reassembled everything before it arrived I have decided not to fit it at this stage. I might if I get significant build up but would appear catch can is working and gave manifold a clean anyway but did not remove bottom section as was not warranted and is significantly a lot of work. Have heard a couple of comments about them causing back pressure issues and triggering egt fault however had several others swear by them and if you realise the amount of work involved in cleaning I let manifolds well worth giving a try at least. I think my older 3.0 litre motor doesn’t have as big an issue as the newer 2.8 litre not sure however. At this stage should be good for another 140,000 kms.
