This is my first post here so if its in the wrong place, ive insulted anyone or even repeated something hopefully the moderators will move this. So Hello everyone.
In the middle of summer I aquired a non running 92 pathfinder from a neighbour who started it as a project and just couldnt get it going. After spending my free time fixing someone elses problems I did manage to get it going but the engine sounded like a bag of hammers being thrown down an elevator shaft. One of the most irritating problems was the intake which seemed to have more tiny splits and holes than swiss cheese. In the end it was more tape than intake. While looking for a replacement part I came across INSYS-USA intakes on Ebay. Less than $50 delivered, so I looked them up and the reviews were acceptable, after all it was $50 and used replacement parts run around $25 or more without an airtight guarentee. After all the rubber at this age could be perishing or split. So I just took a chance.
The Good
Shipping was quick (3 days to the Rockies) and it was packed well. You can see from the pictures that it was cosmetically quite nice looking as a kit and have everything you need. The alloy pipe is smooth and well finished with a dropped flair to tilt the filter down (although I did not use this and may cut it down. The alloy pipe does not feel luxuriously thick, but is sturdy and wont flex under hand strength. The welds are acceptable, without pin holes and seem even enough. The (im guessing here) silicon end pieces are chunky and secure. The filter is generic - A good inspection showed no pin holes or gaps or splits. How well does it filter? I have no way of knowing and I wont even hazard a guess. Im going to use it for now.
The Bad and The Ugly
The coupling between the MAF sensor and silicon was not to the same quality as the rest of the kit. For one it was slightly warped and was not flush. The drilled holes did not quite line up and had a lot of swarf - less than 5 minutes with some sand paper sorted that out (see pix). The real problem was how warped the base plate was, I had no option but to make a gasket out of cardboard and paste - cork gasket material would be much better but I was out. I think with the thin alloy the heat from the welding buckled the plate, to include a gasket would have been a wise decision for INSYS to have made, but no. Never the less it was only $45 dollars delivered and for less than 20 cents of sealent and cardbord I can live with it.
The Universal Mounting Kit - its just a couple of strips of aluminium with a few holes drilled that you bend and twist to get it to fit. Surprisingly it works very well, just looks a bit flimsy.
Installing:
It took me less than 45 minutes to remove the old intake, sand the coupling, make the gasket, assemble and install. It fits perfectly and looks good.
Does it work? Well it works for me. My Pathy no longer surges, stalls and reves all over the place so for me it was money well spent. Does it add horses? My truck is still running badly so I dont have a difinitive answer for you but it comes without a shroud so I can only assume it will suck in hot air from the engine bay. In addition the main pipe is aluminium and will no doubt act as a heat sink, but these are small things easily fixable with a bit of heat tape, alloy plate and a few hours of work.
Personally I love it. Now for headers.
