BLouisGod Posted April 17, 2007 Share Posted April 17, 2007 This is more a FYI than a detailed DIY but it works, I have it on my wd21 and will take pictures when I get a chance. A 87-95 Maxima intake adapter (pictured below) will bolt up to the wd21 MAF perfectly. You'll just need to order the adapter and a 3" cone filter (I used an old K&N from my civic when it was boosted). They run about 20 bucks on ebay - search "95 maxima adapter". You will only need to supply some quality nuts and bolts for the install. Simply remove the stock airbox and plumbing to create space for the cone filter. Remove the box from the MAF and replace it with the adapter and bolts. Attach the cone filter. Place some sort of cushion ( I used weather stripping) on the bottom of the filter so it rests quietly in the engine bay. Done. BTW, its a little high pitched at idle but deep toned under load. I havent really noticed any improvements on the butt-dyno; mpg up around 1-1.5 by the fill tank and divide method... Link to comment Share on other sites More sharing options...

yozsi Posted April 18, 2007 Share Posted April 18, 2007 yea, the stock intake is nice and quiet. why do i want a filter theats loud and soaks up water like a sponge? Link to comment Share on other sites More sharing options...
Jarsiff Posted April 18, 2007 Share Posted April 18, 2007 another thing you might want to keep your eye on is those ebay max adapters are made pretty cheaply and a guy I know in seattle with a supercharged maxima snapped one of those in half. i think its a cool idea and a good find for people who didnt know about it but like i said just keep an eye on it Link to comment Share on other sites More sharing options...
BLouisGod Posted April 18, 2007 Author Share Posted April 18, 2007 Theres actually a metal one on there now that I bought - not the plastic type. Water is an issue, but I dont mud the truck or anything like that so its fine for me, like you said, not for everyone Link to comment Share on other sites More sharing options...
Pavelow Leaks Posted April 18, 2007 Share Posted April 18, 2007 if you leave the filter in the stock airbox position they dont get all that wet, mine was dry as a bone after my alternator killing excursion. Link to comment Share on other sites More sharing options...
Simon Posted April 18, 2007 Share Posted April 18, 2007 Depends on the situation. Flying through shallow mud like you were, you may be right. However, deeper mud, can really get in there quite well. SkinnyPedal drenched his last year on a run in Bobcaygeon, and was lucky that he didn't hydrolock. His ricer cone filter was COMPLETELY soaked. Of course, the mud/water was over his hood.

Trancebear Posted April 18, 2007 Share Posted April 18, 2007 Summit racing makes a filter wrap for those extreme mudding runs. I have one that I will use and it set me back $25. Link to comment Share on other sites More sharing options...
mws Posted April 19, 2007 Share Posted April 19, 2007 yea, the stock intake is nice and quiet. why do i want a filter theats loud and soaks up water like a sponge? To impress all your ricer friends? Link to comment Share on other sites More sharing options...
DJ Dank Posted April 20, 2007 Share Posted April 20, 2007 Yup. People have been doing that for a while now. Revolutionary!!! I wouldn't recommend that way for R50's because I went that route before I got my JWT and had no where to put the vacuum hose that I unplugged from the stock airbox and just zip tied it to hold it tight. But the threw the CEL. The JWT has a vacuum port where you can plug in the hose. This took care of the CEL. Link to comment Share on other sites More sharing options...
