ptownTSI Posted August 21, 2005 Share Posted August 21, 2005 Well the GS needs a new air filter so i finally figured that after all these years of ignoring it and not putting any performance stuff on it (its slow as *BLEEP* anyways) i might try a Cold air intake. who sells a nice one? I dont want one of the $50 craptacular fleagay kinds. Anyone ever change the timing on these things? i've been running 89 in it fine ever since gas hit $3.00 for premium here. but its all factory timing. oh and anyone ever think of taking all those mufflers and cats off on these things. it has way too many. How do they sound with the middle resonators removed and only the front cats and back mufflers attached? anyone make a good exhaust cat-back for these? my stock grand cherokee ran 14.8's @ 90mph so since gas got expensive i've been driving the lexus, and i cant stand how slow it is.

Silverback Posted August 25, 2005 Share Posted August 25, 2005 I have been considering buying this from ebay, but I too am not sure about the value here or to simply buy a drop in K&N filter. Plus this comes without instructions, does anyone have experience with installation http://cgi.ebay.com/ebaymotors/ws/eBayISAP...mMakeTrack=true For those who know, please let us know the best cold air product or if the BFI approach (I have a SC400 as well) will work? For a 2001 GS 300 Cheers Quote Link to comment Share on other sites More sharing options...

And the only piece that you have to cut off is this restrictor [ see 3rd pic ]... Which can be easily epoxied back on if you choose to go stock again. This should work for your 93.

Cheers ← The intake mod will work on your 01, Mine is a 98 same thing basically. Search ebay for a inexpensive short ram intake with the filter [ you need the rubber ring on the filter to epoxy on your air filter box ] Then cut the polished tube down on both ends to fit in the space that exists between the throttle body and the airfilter box. Use the silicone adapter for the throttle body end and the other end slides into that rubber air filter ring that came with the tube. It is really easy and I could feel the difference right away and it is still quiet. Your email is listed private ? Can't send those pix.

dcfish Posted August 25, 2005 Share Posted August 25, 2005 I tried to PM, but it didn't work? ← Sorry for the different size pix but you get the idea. The rubber ring is what you need from the conical filter that comes with the intake. And the pic of the air intake sensor mount is the part you cut off of the air filter box[ there is one on your new intake welded on ]. You epoxy the rubber ring onto the filter box. Then cut the intake to fit. Done deal. Quote Link to comment Share on other sites More sharing options...

Is there one that you are aware that will cross over into 2001, or do I need to get the one in the previous link?

Maybe a IS intake has the same mount for the sensor. Check that out. Quote Link to comment Share on other sites More sharing options...

Sorry about my ignorance ← The cone intake will just suck in the hot air from your engine bay , While the stock setup is cold air and sucks in cold air from the outside. The metal tube is a larger diameter than the stock tube and less restricting. ;) Oh yeah, It looks clean too.... Quote Link to comment Share on other sites More sharing options...

It wouldn't hurt to give the engine bay a cleaning also. ;) Quote Link to comment Share on other sites More sharing options...
