which is the best intake for the FD im thinking bout getting a HKS RS but is it worth the price? why is it so much? what about pettit, M2, ARC...

 

NO. If I am not mistaken the HKS is the most expensive...I went with the Greddy Airnx for the twins and it was abotu 300+....I wouldn't spend that money on an intake now that I think about it. Go with the Pettit. Not so pretty but cheaper.

 

i think so

its has hard pipe and hks did their homework on this one

u will not be diappointed

 

IMO no matter what filter you get it's still going to suck the same hot air in (unless it's a box type or comes with heat shields)...With the sequential twin setup you have about 4-6 inches forward and a few inches side to side to move the intakes around...IMO the only homework that was done was...."It seems to fit good...put it there"

 

God damn! pettit wants 400 for that damn ugly thing with KnN filters?

**** all of them....Get the ebay hard pipes and fab your own.

 

Not at all -- you are basically paying out the *** for some little 1" fittings. Someone posted a few pics of their intake that they made which resembled that of a HKS RS, only they did it for 1/4 of the price. Also, hardpipes on ebay are not that expensive. Same goes with those foam mushroom filters.

 

You know, now that I think of it...He'll probably go buy the HKS or something like it...When I was in his position a couple years ago I thought nothing I could make would be as good as what manufacturers have already R&D-ed and manufactured....If you want to save money then this would be the one thing you really can't **** up.

 

I'm personally planning on getting some Ebay hardpipes, 2 K&N cones, and some aluminum sheeting and doing some fab work. It's insane how much people want for FD intakes.

The only thing the HKS kit has going for it are the hardpipes, which are nice, cast aluminum and are of great quality. But, it's not THAT nice! You're not getting what you pay for.

I doubt one intake will make more power than another intake. Use a quality filter, get some cold air sourced to the filters, and you're done. It would probably take a good Saturday to fab an intake with trips to the hardware store - it's just not that tricky.

Hmmmmmmm.............. What's the best intake

How about a really inexpensive ($70) mod to your stock airbox that will perform better than the M2

Yeah, I custom fabbed up an intake and heat shield. All the open filter type intakes are pretty much the same.



I just got some hard intake pipes (similar to the ones on Ebay), 2 KN filters, 1 breather for the air pump, and made a heat shield from "Damian"s template. Do a search for his name. I also ran an air scoop from the passenger side "oil cooler" opening to the intake. I just got a CWR intake box from a friend, so I'll do some comparisons with that later on.

 

I have the hks rs intakes and I love them, to me it was worth my money...looks great too..

 

I have them, they are only worth the money if you like the look and the name, outside of that... its just an intake - not even CAI.

 

i bought them used and love them, got them cheaper used too so it was all good.

 

I'd agree that a modded airbox is a great idea (or a pod/box setup, if done right), and one that should be promoted - but some people, myself included, are looking towards a fmic or vmic setup - so it kind of makes a stock setup a moot point.

as for the hks intake - great pipework, but still uses foamies. I don't like the idea of foam in an FD engine bay - I'll conceed that regularly swapping them out solves that issue - but my idea of a good pod, is one that can be pulled out, tapped, oiled, and put back in. I'd rather buy a can of oil every few years, as opposed to an exxy replacement filter every 6 months or whatever

 

i was lucky my car came with the hks setup in it. Guess the great thing about it is its basically drop in, no mods necessary and no screwing around needed. Dunno about the states but the filter elements in Japan are very cheap. I got 2 brand new ones for 5000 yen.

ALso got HKS intercooler hardpipes which were a nice addition.

 

couldn't agree more. but many people have afteramarket intercoolers that force us to eliminate the stock airbox.

 

My biggest reason for wanting an intake is to never, EVER have to deal with a stock airbox again. Mazda went out of their way to make it cumbersome and a pain in the ***. Just checking the filter to see if it's dirty is a chore.

I do applaud the design you came up with for modding the stocker, though. To me it would be more worthwhile if Mazda had made a decent airbox to begin with. My "decent" I mean easy to check and change the filter, and not in the way. It fails bigtime on both counts.

Dale,

You are correct about the stock airbox filter being inconvenient to check. Mazda should have designed the box with the air flowing from the top to the bottom. The intake pipes should have been on the bottom section. This would have allowed easy removal of the top section for filter replacement. After removing mine countless times, I have gotten used to it, and can do it in about 5 minutes. The filter elements don't need cleaning, or replacing very often, even with my mod. I checked my K&N after about 5K (just over a year), and it didn't need cleaning.

That being said, it is always a pleasure to change an air filter in ANY other car after doing the stock filter in an FD. Of course, ANY work on another car is easier and more accessible than the FD

 

No doubt! My wife's Lexus SC300 has the world's easiest air filter. Two clips and a flap opens up, then you slide it out. It's stupid easy. Mazda has never made an "easy" airbox - the airbox on the FC was also a pain in the butt to check. Remove the intake tube (3 10mm bolts) then unbolt the 10-15 10mm bolts that hold the two halves of the airbox together. That's a lot of bolts!

I do highly recommend running a GOOD air filter. I'm not keen on the foam air filters - they just let too much stuff through, and that's really hard on a turbo. K&N type elements do a great job, though.

Sounds like my Tacoma air filter. Hmmmmmmm Lexus and Toyota ........ maybe there is some sort of link between the two.

Of course, any pre 70's air filter can be changed by spinning off ONE wing nut

 

The HKS intake foam filters are easily replaced by the angled K&N filters.

 

Ford does it this way as well -- easiest air boxes to work with.
