I installed a Airaid elbow and a drop in K&N yesterday.

Also deleted the sound tube.

It took 20 minutes or so.

Very pleased, didn't want a open air filter.

If anyone is looking for a K&N drop in for the OEM box, let me know. It's part number 33-2431 and was used for less than 500 miles. It is washable and reusable.

Makes for a clean looking engine compartment. Believe that's a 4" dia. conduit while stock is 3.5". Time for an 84.5MM TB now. However, my thoughts are with 3.5" opening for the stock TB and exit from air box I wonder if any gain of air flow is derived? Restriction maintained still at either end.

The stock intake tube has the silencer (bottom diffused air flow part of tube) and a sound tube both, one quiets and other makes noise lmao. Must be different sounds? Am in neutral on this one but seems with the larger 84.5MM TB air flow is fairly maxed out with stock 3.5" tube. Meaning with the larger port and butterfly valve more air is flowing, like turning a faucet on full blast vs maybe 3/4 wide open with OEM TB.

Must be careful and not lean out though too much. Appears to be a problem with 90MM TB without additional tune (maybe injector change too). So that's the end of TK if so equipped. Nope, the concenus is the change works great (84.5MM TB) but no actual gains documented. No HP increase either with open filter box and intake larger untill a tune is added. In my HO only again, it's strictly the tune as what all the advertising and hype is based upon.

One last thing, wonder if any intake heat saturation is present? The stock intake is wafer thin and enough heat in engine compartment to warm things up. Possibly not as air flow may have enough velocity to not be affected much unless idling. It is supposed to be cold air intake with a Ram Air theory. At least the definition as it goes from the late '60's. https://en.m.wikiped.../Ram-air_intake
