Here's the thing, it comes down to a K&N vs. SW filter, not any of the other weapon-r intake.

Take a look at zombie's system above and my system again on page 6 of my link below, you'll be on the right track.

I get some issues with the idle rpms with mine, because my exhaust is all wacko for one and also the open ended design of my intake (no filter), and you won't need to worry about that.

the ram air to the spectre air filter was too much maintenance. i had to clean the filter every couple of hundred miles, so the ram air part wont get restricted from dirt. every time after i clean the filter it feels like i gained power (probably in my head), but after a month my gas mileage would suck and it would feel sluggish.

i think the design of the dragon heat shield is kinda crappy. your torque is going to suffer because its gonna take much more time for cold air to travel from the bumper all the way to your intake manifold. ram air doesn't really work until about 70 mph, so power is going to suffer until then. thats why i put back my stock filter box and connect it to the ram air horn. im not sucking in hot air and cold air is ready if i want to floor it at a stop or low speeds.

the heat shield is made of a sheet of aluminum metal and the out side is wrapped with self adhesive foam and foil insulation. its all held together with rivets and aluminum tape.

zombie so the wr ramair tube can fit through the hole of the bumper resonator? i like your shield that was a kool idea you notice a big improvement with that over ram air? what else you hop up on upgrades? thanks, ps what was smart was adding that foam for extra kooling making sure no heat seeps in... great job ... also how did you get wr ramair to sit in front bumper hole? thanks

i made the ram air with a big oil funnel, jb weld, and a 90 degree 3 inch honda civic aftermarket intake tube. the oil funnel has a small plastic tab w/ a hole already on it. so i just zip tied that to something.

i had the heat shield and the ram air running at the same time, but too much heat was still getting in. so the power gain was probably minimum. im happy with my stock air box w/ ram air.

you know what bro for some reason our rx has unusual heat compared to some other vehicles, i was thinking what you were just saying... if i use the wr sw intake kit with ram air wouldnt warm air suck up, you think leaving stock airbox and just adding ram air tube to front will be better since the airbox covers filter and the tube ramair can bring cold air to oem airbox? i currently using a k&n dropin replacement... what yu think zombie, or lexmex lol thanks what would deflect heat better the rubber tubbing to filter or wr aluminized pipe to filter. thanks especially summer comming up its gonna get really warm...

Rubber usually does a better job depending on how thick. I use some steel tubing up top. PVC is probably the best stuff.

you have pics of that resonor piece aswell as the resonator that connects to oem airbox trying to figure out if the ram tube i got will just clamp on to that airbox or something? will ram air cause cel lights to go on? or upgraded filter intake thanks lex

Take a look at this thread, https://www.clublexus.com/forums/sho...d.php?t=158249

TunedRX300 originally did the ram air intake for the RX300 and he has a picture of the resonator.

I get cel errors because I don't run an air filter, but they far and few right now.

Default ram air filter

ok lexmex or zombie advise me gas prices are going way too high, back in the days when 91 octane was under a dollar a gallon this rx only cost 30 something dollars to fill up, now it has more then doubled, i need advise should i add the complete wr sw intake system or if i add wr ram tube to factory filter, what you think will be a better choice summer is comming and warmer air means more fuel consumption.... if the metal intake and sw filter have no heat shield is it best to just add the ram air tubeto factory airbox as you said lexmex that as long as the rubber is thick it dissipates heat better, so i was thinking adding the ram air tube to factory airbox with my dropin k&n filter so colder air would be recieved from the tube, or i was thinking just go with tunnedrx300's idea for 15 dollars? thanksalso with the oem resonator in bumper does it even have a hole to supply the cold air to oem airbox or its just closed and there to quite intake system of oem thankscan someone link me the thread on tunedrx300 custom ram air i have looked online and cannot find it... thanksalso did anyone buy the original ram air tube by wr? i wanted to see pics or have a suggestion on how it connects from airbox all the way down thanks

Thread I posted just above described TunedRX300's intake. You lose nothing in trying his system (easiest to implement in my opinion).

bro lexmex i saw that resonator i can't believe it had no hole for the air hole in the front bumper for air to pass up to the airbox, it looks exactly what you siad a resonator the only hole was to connect to oem airbox without recieving air from bumper corect me if i am wrong thanks bro, damn i went to home depot but all i bught was an extentioncord... was thinking about that stuff you and tunned did.... they all look kool
