K&N intake kit or Hight flow filter with ram air

**oborony** · 02-20-2010, 12:44 PM

Hi everyone i just bought my first 98 ls1 Formula and im very proud i did. It is already moded and tuned with juice. One thing i would like to do is add a better Throttle Body and an MAF but i dont know what to do with the intake. Right now it has an SLP lid fram paper filter and a ram air box kit its like a scoop under the bumper, infront of the radiator. Should i get an K&N intake kit and take out the ram air box or get a better box like the FTP and high flow filter for it?

If it is plastic that ram air is a ssra(super sucker ram air) nothing wrong with it, nor your lid, or your current filter. Maf is able to flow well past what you can put down. You could upgrade to a ls-6 intake manifold which would require you to delete the egr system unless you find a slp modified one with egr in it. Look up shaner throttle bodies everyone who has had there's ported seems to be happy.

keep the intake setup you have. the k&n intake kit is trash. the ftp lid is also trash, flows good but is made of thin plastic that cracks easy. get a hi flow filter for that slp lid and be done with it. the stock maf is fine also.

Thanks guys. It is the (super sucker ram air) butt the front scoope peace is craked pritty bad

. do they sell just the front peace? if not i could just fix it up. So here is what happend my check engin light was on after i took it to a carwash. So i whent to my tuner he hooked it up and there was no air respons so he thought it was the MAF not responding, so i ordered an SLP MAF the 85mm. it was friday so i call back monday they found out an O2 sensor wier was blown bc the O2 sensor was loose and it got wet so they fixed it i payed 60 bucks no big deal. but now i got an slp 85mm maf that was like 200 bucks sitting around for nothing. the car has a BBK SSi intake manafold im thinking i order a 85mm BBK Throttle body. What i would like to do is fix or replace the super sucker ram air, add the high flow filter, add the slp maf and bbk throttle body. what you guys think good idea or not worth it for the money?

**c5z28** · 02-23-2010, 01:03 PM

If you port out the bbk to 85mm(prevent bottle necking) then it would be worth it for future mods like a cam. Problem is some people need a tune for the slp maf and if that is the case it would be a waste of money for the 1-2hp you made with the maf.

you givin bad info buddy. k&n does not filter worth a damn. paper filter is better

My experience with filters, 2x each at the drag strip with my WS6, the trap speed was no siginificant difference between: no filter, clean K&N, clean AC Delco.

K&N works wonders on other setups, but nobody here will tell you they do much (if anything) for our F-bodies.

**oborony** · 02-24-2010, 04:13 AM

yeah it has all that crap. its got a custum built cam probly the bigest you can go for it. has a full exhaust with cut out, timing tunner, valve springs rods pistons rebuilt cylinders, bbk manafold and thats all the mods as far as i know. othere then the nos. they guy i bought it from said it has like 440 some horse. and over 500 when sprayd. the throttle is polished inside. i think the slp maf and the throtle and high flow filter will help it all though the paper ones do filter better i looks like to me

K&N is better then a paper filter what makes you say that its not. Most if not all of racing uses k&N filters anything from circle track to micro to drag racing. Also when you hear about people saying that K&N's let more dirt in those people are simply wrong. Every dirt track car uses a K&N filter simply because they are the best.

Stock MAF is good for at least 600 RWHP...

I run a fram in my car and I wont never put another K&N in my car. I get alot less buildup on the MAF and TB with my fram, the K&N always seemed to have crud on everything. There isnt any power difference between the two either, also I can buy 5 frams for the price of 1 K&N.

sounds like you may have over oiled... personally i like k&n and have had zero problems with em but i guess to each his own

no way dude. i understand some racers use k&n but keep in mind they also go thru their engines alot more than our daily drivers. take your kn out and hold it up to light. you will see bright holes-that is where dirt gets thru. its an old and obsolete way to filter air. synthetic media filters are 10x better than kn and a paper filter is better also. you cant tell me a drop in kn filter gave you enough power you could feel it. that is your imagination. also another trick-smear a lil bit of wheel bearing grease right under that kn filter and run it for an oil change. pull the filter out and look at the dirt on the grease. dont worry, your engine wont suck in a small smearing of grease

What kind of cam details! What product is that timing tuner? I guess I would find a machine shop and see what you could do about opening it up, if you look on tech you can port the runners if in the very least to get rid of the casting marks.

The "greese" your talking about is when people over oil the filter when they clean it. I work with a man who sells this stuff along with lucas oil products and other racing products and he put it the best way possible. People who sit on the forums all day probably dont know as much as they think until they really dive into the products.

your not listening to me. you physically take some wheel bearing grease and put it under your airfilter on the bottom of your air box. this is to prove it will let dirt through the filter because it will hit the grease and stick. and lucas isnt the best either.

o btw: i dont sit on forums all day, i am gm technician that works on these cars every day. trust me i know what i am talking about

**jetaws6** · 02-25-2010, 05:32 AM

Ok whatever you say

**jmhvenom** · 02-25-2010, 05:40 AM

Under the air filter would be pre filtered air... wouldn't you want to put it on top of the filter??

no... the oil on them pieces of junk make for dirt cakes and very little airflow... people who are sponsored by K&N use them... i have several friends that race on a dirt track (grand view speedway) near me and none use K&N...
