Cold Air Intake for JK 3.8Lt

[Cherokee30D]

Hi there, yes me again with another query.

Just wondering if anyone has fitted a cold air intake to their 3.8Lt JK?
If so, what are your findings re: power, economy etc.

I like the idea but need to know if it's worth spending the $.

Thanks in advance, Craig

I've got an airaid which I bought second hand, and to be honest there is negligible difference to the stock air box. Only difference is a high frequency whine at certain speeds.

Want cold air....I'd add a snorkel to the stock airbox. Water safe.

The Cold Air Intake thingy will not make a scrap of difference because over time the ECU will simply readjust its settings to any temperature change and airflow so as to stay within parameters set up prior. Save your money and have a holiday.

Looks like I might put the money towards a holiday as suggested......

Cheers, Craig

Not a "cold air intake" as such, but I fitted an AEV snorkel to mine, when the gauges that read from the OBDII port said I had intake temps over 45C. I was also getting pinging any time I drove up a hill. And I live in the Mountains...

Tried different fuels, ECU programmer etc, no go. What finally fixed it for me was the snorkel. Rarely get any now, even on hot days & inlet temps have dropped to usually no more than 5C over ambient. (Higher when idling at lights as the air spends more time under the bonnet to heat up.)

No measurable change to economy or power (as measured by the 'butt dyno'), but that wasn't why I put it on. Also, I don't stress during water crossings. No difference measured by rotating the ram head backwards, (though this apparently does help on the CRDs), or from the Donaldson Topspin precleaner I have on it now. But the filter does last much longer between changes!

I put a Banks CAI on my manual jk and love it. Much deeper/throaty sound, not sure about performance gains, but would do it again.
