Spectre Performance 9943 Cold Air Intake

Does anyone out there have this air intake? If so anyone live near Tuscarawas County in Ohio? I think I'm interested in getting it but I wan to see it in person before I make my final decision.

Not close to you but I have one. Wrapped the tube in header wrap though to help keeps temps down. It freed up room for my OBA compressor.

The issue is that K&N's air filter have been found to be the absolute worst filter for actually providing an adequately filtered supply of air to the engine. Using a K&N air filter on your engine is like expecting a screen door to keep the dirt and dust out when a dust storm is raging outside your home.

A scientifically conducted ISO* test of various air filters produced some very telling results. AC-Delco's paper element air filter came in 1st, K&N's came in dead last. And since the Wrangler TJ's OE air intake system was specifically designed to be totally non-restrictive (flows more air than the engine can possibly consume) plus the factory filter has so much surface area that it is non-restrictive as well, there is not even a performance-based reason to go with a K&N.

There are SOME restrictive air intakes in some vehicles that could benefit, performance-wise, by installing a replacement but the TJ's is not one of them.

The below chart and the text below it is quoted from the ISO test...



"In the chart above it’s important to note the different test durations for each filter. The AC Delco filter test ran for 60 minutes before exceeding the restriction limit while the AMSOIL and K&N tests each ran for 20 and 24 minutes respectively before reaching max restriction. In 60 minutes the AC Filter accumulated 574gms of dirt and passed only 0.4gms. After only 24 minutes the K&N had accumulated 221gms of dirt but passed 7.0gms. Compared to the AC, the K&N “plugged up” nearly 3 times faster, passed 18 times more dirt and captured 37% less dirt. "


*ISO 5011 Test:
The ISO 5011 Standard (formerly SAE J726) defines a precise filter test using precision measurements under controlled conditions. Temperature & humidity of the test dust and air used in the test are strictly monitored and controlled. As Arlen learned in attempting his own tests, there are many variables that can adversely affect filter test results. A small temperature change or a small change in humidity can cause the mass of a paper filter to change by several grams. To obtain an accurate measure of filter efficiency, it’s critical to know the EXACT amount of test dust being fed into the filter during the test. By following the ISO 5011 standard, a filter tested in Germany can be compared directly compared to another filter tested 5 years later in Rhode Island. The ISO 5011 filter test data for each filter is contained in two test reports; Capacity-Efficiency and Flow Restriction.
not really much to do with this filter, but long story short CAI will do nothing for your jeep because of the way the airbox was designed.

It's not so much the "cold-air" aspect as the raising the level of the intake without going to a snorkel for when I am off roading. With this intake system I have read that even if the water is rolling over the top of my 1/2 doors I am not getting water in the intake. I'm not exactly looking for more performance with it, I just want my motor to be a little safer if I go thru some DEEP water. I know all the statistics as far as every one saying, " this will do absolutely nothing to improve fuel milage or horsepower." I know already.

Just to play Devil's Advocate here... If you install this thing as instructed, aren't you risking that any water introduced into the cowling will also be introduced into your intake area???

Wasn't this exactly what you were hoping to avoid?

Think about it though, for the water to come in thru that it would have to over 4 feet deep. Rainwater won't bother it because if it did it would fry the electrics for you wiper motor, cuz that's where it's mounted. Plus to help keep rainwater out I would install a scoop there that will also help with airflow into the cowl.

You could do the same, but with a better filter MUCH cheaper.

Chevy air box with intake hose going to the cowl. That way you could use a real filter and be drawing your air from the cowl area.

Want to explain a little more about the Chevy air box... like model of chevy? I want to do this intake system, but don't want to have the filter in the cowl because it would be pain to change, plus a paper filter seems to be way better way to go anyway.

Here is what mine looks like now.


My plan is to eventually run a 3" hose from the cowl to the airbox.
Like So.


The filter and air box comes from many of the mid 80 to mid 90's GM's with the 3.8 litre engine. Mine come from a 89-90 Pontiac Bonneville and was like $12.00 from the local U pull it.
Or you can go to Fram's website and do a quick part search for CA3916 and it will list all the models with that filter box.

I have the spectre intake. It makes the jeep sound tougher because you can hear the engine much better. I dyno tested it and it didn't make significant gains. For me it was easier to buy a complete intake than go digging around the junk yard to fine the other air boxes that work. There are drains in the cowl so it can take on a moderate amount of water, but if you have the cowl under water, then you better have spent many many hours water proofing everything in the dash! Getting fresh air is never a bad thing. I've seen IATs over 175F with the stock intake on slow trails. I haven't had this in the desert in the heat yet, but many times I run ambient to 10F over ambient. My stock intake was more like 20-80F over ambient while it sucks that nice hot radiator backwash under my black, sun baked hood.

The cowl is horizontal...with vents on top.
How are you NOT going to get water in there?
Rain, washing, etc?

When you are in water that deep what do you do about the exhaust? The water puts pressure against the end, radically increasing back pressure - till it dies.
Once it dies the pipes, muffler and cat as they cool "suck" the water back up the exhaust, if the cool water hits a hot valve - pretzel time.

Even if it doesn't get that far up, you now have as muffler full of water - often too plugged to run. Look at a military vehicle that's ready for water - BOTH intake and exhaust are brought up.

But - without modifying both ends, you can impress Jr. High kids at the mall.

The cowl has a drain to get rid of the water. You not going to get anymore to engine then you would with the stock airbox.

i was interested for the same reason.. raise the height of the intake.. works well for that and the filter is offset from the vent so no worries about rain, snow ect.. no problems there..

that being said.. after a couple months i took this off my jeep.. this thing is LOUD. it was a novelty at first that quickly became very annoying.. I would not recommend this product to anyone for that reason

oh.. and if anyone wants it.. i will give it to you if you want to pay the freight.. only part missing would be the little flange that goes thru the firewall.. just sitting in my garage and will get tossed when do a late summer cleaning

Any water that gets into my muffler will just as easily run right back out, I've go a straight cherry bomb glass pack. So I'm not worried about water getting into the exhaust. The water would have to be REALLY deep for it to shut the motor down. How many videos are there of stock 4.0's running thru 4 or more feet of water for a long ways w/o any trouble whatsoever? Just saying.
