IAT in dual snorkel air element

Hi guys,
I plan to put a dual snorkel air element from a L69.
I'd like to know if the dual snorkel air element has already the hole to install the IAT sensor or I need to drill one?

Re: IAT in dual snorkel air element

Well if you have to drill one is it going to detour you from buying it? It seems to me that it wont. So if your okay with drilling it, then just get it and see.

While were at it, where is the best place to locate the IAT? I thought I remember hearing it is too close to the engine where it already is. Too much heat.

Re: IAT in dual snorkel air element

I have a kn filter. I drilled a hole and mounted it in there. I thought about mounting it in my cowl but I dont really think it makes much of a difference.

Re: IAT in dual snorkel air element

I have been looking for the info, but I haven't had much luck. I remember that relocating it to a cooler place, e.g. the duct going to the air cleaner would boost performance by tricking the ECM into thinking the air is cooler than the stock location.

Re: IAT in dual snorkel air element

Yes relocating the IAT in a cooler place is the great deal.
But, under the hood, the limitation is the lenght of the wires, and with the hot air from the engine, the air cleaner is a good place to install the IAT cause fresh air enters directly in the stock air cleaner box. Others places under the hood are too hot.

Re: IAT in dual snorkel air element

You will need to drill the hole. And you'll be limited by the length of the wiring to the sensor, so you'll have to drill the hole in the same location as it is in the stock air cleaner(in the rear of the air cleaner). But the bottom of the dual snorkel air cleaner is curved where you'll be drilling the hole, whereas the bottom of the stock air cleaner is flat at that spot, so after you drill the hole, you'll have to flatten the bottom of the dual snorkel air cleaner at the hole(a few taps with a hammer will do it), otherwise the sensor won't snap in and stay in. When you compare the two air cleaners, you'll see what I mean. But it's not a big deal to do, so no worries about that.

But now comes the not-so-good news: the dual snorkel air cleaner won't simply swap onto a TBI engine. The air compressor(thanks to the serpentine drive configuration) stands too high and wide for routing the intake tube from the snorkel to the air cleaner on the passenger side; also, the plumbing on that side stands too high for the air cleaner to sit down properly onto the throttle body. Again, you'll see what I'm talking about when you try to mount it.

So to keep this post from becoming dreadfully long, I'll just say that with some creativity, you can make this work.

Re: IAT in dual snorkel air element

I think air compressor is the AIR pump, not the AC compressor?
I've already read that the AIR pump is a problem but i will delete it with a pulley already bought.
Thanks for the help. I've never noticed I have to flat the curved bottom of the air cleaner.
When I'll do the job, I'll take some photos to help other members.

Re: IAT in dual snorkel air element

Do you have the passenger side duct for the air cleaner? You might wanna consider replacing the radiator reservoir with an older one. It might be in the way of the duct.

The air (conditioning) compressor; it's in the way. It's large, and it's mounted too high and too wide for L69 ducting.

The L69 intake was designed around an alternator, not an ac compressor. The alternator is much smaller than a compressor, and it wasn't installed in a serpentine drive system, so it was located much lower and closer to the engine than a compressor is in a serpentine drive system.

The AIR pump is below the compressor, so the AIR pump, itself, isn't in the way. However, you might be thinking of the AIR diverter, and, yes, that is also an obstacle too. But if you're deleting the AIR system anyway, then that won't be an issue for you.

Re: IAT in dual snorkel air element

LA is correct...I epoxied mine IAT into my KN extreme assembly. Looks a lil hokey but you really cant see it with the air cleaner on.
