Hey, hey, you snipped that at the wrong place, the LAST thing I am going
to do is to endorse that POS product.
As far as I am concerned, it is not far from the Vornado in lameness,
and I am ashamed to have shelled out $200.00 and then installed on my
car, even if it was 10 years ago.

Hell, the Vornado probably will not damage the engine the way that
Jackson Racing's Cold Air Induction has done to thousands of Miatas.

Let Jackson Breaking sue me, it is truly squeezing a turnip and they
know that this product is a turd. :-)

What I wrote in the previous post was this, please note the parentheses.

"I did run the JR CAI with the oiled foam filter for about 2 years and
never had a problem with it, (the filter that is, the actual JR CAI unit
was a poorly-made nightmare)."

I hate the JR CAI, absolutely hate it. The thing developed cracks on the
bottom where I could not see them.
When I took the air filter off and saw a pecan tree twig that was at
least 1/16" of an inch across underneath the filter, I could only shake
my head and wonder how many small particles had dusted the engine.

Jackson Breaking Products is what I routinely call them now. I have seen
about 7 or 8 of those JR CAI's close-up, and every one of them that was
over a year old had cracks in it.

If I am looking at a Miata to buy and it has a JR CAI, that is a huge
downside as the engine has probably been dusted, the filter over-oiled,
or both. Most likely a JR CAI will be a deal-breaker since there are
endless models to choose from out there.
It would also make me need to find a new intake immediately, though I
would just order up a Randall unit.
Still more noise change than anything with the Randall CAI, but at least
it is not destructive to the engine and I can see if cracks starts to
appear in the carbon fiber air tube.

I really wonder about the person who designed the JR CAI And thought
that you could mount a plastic air filter box on top of the radiator,
and towards the hotter side of the engine without having trouble with it
becoming brittle and cracking.

I sold my used JR CAI and felt really bad about it, but the buyer could
not wait to get it home to damage his engine with it too.JR XAI SUCKS!

Now that just hurts.......That price seems to slip down all the time.

Make that, the JR CAI sucks! Also, that was endless used Miata models to
choose from.
The 1990 - 2003, (or so), Miata is so cheap and plentiful that is only
makes sense to find a good one with only the "good" mods, if any.

The Randall tube is on the dirty side of the filter anyway. Mine is a
rather loose fit, and isn't stressed enough to crack. In hot weather
(>80F) it lets me run 89 octane at 14BTDC with no pinging, whereas I
used to need 91 in summer. IOW, it doesn't really add any power, but it
helps prevent loss of power in hot weather. If that makes any sense.

In my opinion, the Randall unit is superior in every way to the Jackson
Breaking Unit, except for the need to cut into the firewall with the
Randall, which is no big deal to me.

I am pretty sure that Jackson Racing hired an engineer from GM to help
design that cold air intake. (that was just for you, Tim). ;-)

Nah, Lucas. The original plans called for Whitworth fasteners. The oil
leaks were tolerable, but they fired him after an argument over cloth
insulation for the MAS wiring.

hi,

the car also has a k&n filter, how do i determine if i have over oiled
it?
this car was getting ~28 mpg before rebuild. i did add a "power box"
fuel management unit from miataMania to eliminate detonation. i do
not see any way to adjust that unit tho. i dont think it can be a
vacuum leak as i dont think the car would idle at all if there were a
vacuum leak.

this car is my wife's daily driver so i dont get to is as quickly as i
would like at times so i havent tested the iat, (which looks like it
is the issue), however, i see that the 1.6's have a trottle dampening
devive, (a dashpot?), and i wonder if i can use one with this car.
the issue i have now is exactly like a 68 mustang w/o a dashpot. ...i
can get the car to the idle position by tweeking the pedel and it will
then idle nicely, but when rpm drops which stopping...well you know.

i'll get to the iat tonight or tomorrow,

thanks,
peter
