K&N oil... You can buy it at any pep boys or advance auto parts store. You should also get the cleaning spray as well to clean the filter.

thanks bro, filter normally around 50 bones?

 

i had a similar experience. my buddy and i both have 5 speeds.
mods (at the time):
me: intake, header
him: intake, header, cat back exhaust
when we would race to test out our mods i would always get him. he'd be at my back bumper. i know it sounds weird since i had fewer mods at the time but everyone was saying it was because my buddy's car was very free flowing. basically when your car breaths really well you lose a little low end. keep in mind also that it was only 1/4mile races, not highway or long stretch. if we would've raced long distance i'm sure he would have caught up and passed me. when you install a header and cat back combo your going to lose a little low end, but you gain very good high end. i'm not sure if you noticed, but with a stock header and exhaust lancers take forever to get from 80mph to 90mph. it basically drags/stalls. now after you install these, it keeps going like normal. nice and quick, because you gain high end. its good to have some back pressure.

 

A good, proper header doesn't lose low end power, unless a 4-1 header. On a lesser displacement vehicle, an intake will lose a bit of power on the low end.

I had an OBX header on my LS coupe, and I didn't lose any power comparing to stock powerband. By no means, I ever thought OBX made the best products. I improved my low and midband and little on the top end since I had stock exhaust.

As for brand name intakes, I'm not really sure it really matters. I had an ebay special for my stock S13 240sx . . . had a bit on the mid to topend, but the car was really a beater on its last leg.

Also: do both of you had different rim size? If you have 17's and he's still stock 15's, the 17's will launch slower.

 

No same rim size, also another question, when i get to 4th gear on the interstate, the car will be real high RPM but then you hear them drop. Almost like....(well if you where here i could make the sound LOL) but anyway it starts out a little higher then immediatly drops. I guess this is good b/c the rpms drop a bit but it also looses top end or does it?

 

so, when is it good to install a test pipe? you guys are making me want to put my cat back on... just recently i swaped out my CAI to SRI.. it was great at first cause i gained back the strong pull of the line... but then lost it in the high end... so i went back to CAI cause i really like the pull in the high end.. now if i take off the test pipe and have my CAI in.. u think i even out the low end and high end probs? or just leave it as is...??? no exhaust by the way... pure stock for now...

 

Kelspar: Yeah, I agree with what most people are saying. I think your CAI and Header are loosing you some low-end torque.

After installing my AEM CAI, and my RRM header, I noticed a tiny loss of low end power. It definitely picks up after 2500 rpm's though. Once you add other mods, this should go away. It's only temporary.

wait im confused? Are u talking about when the car auto downshifts to 3rd for more power than shifts back to 4th?

 

No when i am on interstate (not related to racing) and i hit forth gear it starts as high rpms but then drops. Bear with me...lol VROOOOOMMM(higher)......VREEEEEMMMMM(lower) and drops from about 4.5-5k to around 4 or below.......like it is an immediate lose in top end, i also havent noticed to much gain in top end. i am dropping the cat back on as we speak ill be back after i finish.......

Well just finished putting the cat back on (not to be confused with cat exhaust), and its much quiter, letting it idle after i reset the battery. Hope this will restore low end a bit, going to race my friend again, also i did my homemade ground kit a few days ago, hope this will help smooth out my idle.

 

I have SRI....

 

perhaps he pushed the pedal harder than you? jk
