can RACING FILTERS increase power of my 97 GLXI A/T

[glb10570]

Im planning to install racing filter for my 97 Lancer GLXI A/T. Does it increase power specially when going uproads? What type or brand is reliable? if not, what can be the best option to increase power?

[1D4LV]

it will technically, but imho, no significant or noticable increase.
together with this, i suggest a change of headers and exhausts to a bigger one...

K&N and HKS are the best universal fit brands.

Yes, a filter will increase power, but alone, it will only give you about a 2-3 hp increase. Not easy to feel that on an automatic. And in traffic, heat soak will bring engine power back down to stock levels, unless you install it as a CAI (cold air intake) or with a heat shield. The heat shield will prevent some of the heat soak, but not all of it. The CAI assembly will give you cold air, all the time, and will bump power to around 5 hp higher than stock, but it is vulnerable to water ingestion in wet conditions, as it puts the filter very close to the ground.

Best bet for more power? Filter+muffler+exhaust pipe upgrade+headers. Just make sure your headers aren't too aggressive (4-1). Stick to a narrow tube 4-2-1 design to maintain torque, as these modifications, when put together, will give you around 8-10 more horsepower, but will have a negative affect on torque. And on an automatic, loss of torque will make your car very sluggish at low rpms.

To keep torque on a car I modify, I usually just go for racing filter + midpipe + muffler (to remove the resonators and catalytic converters). This makes the car kinda noisy, though.

cold air intake maganda para mataas ang gain sa hp kasi nga malamig na hangin nakukuha nya!

[yebo]

going uphill? di ba dapat torque ang i-increase mo at hindi hp? besides if you go to the k&n filter site, the hp curve does not even depart by 1% from the stock hp curve until it gets to around red line already. what good is +5 hp if it comes only at 6400 rpm (red line for a lancer glxi)? i doubt it if glb10570 would ever step on the gas until the engine is at 6400 rpm, not even close. low end torque dapat ang palakasin and not hp.

In My opinion sir...


stick to stock nlang po..


kasi A/T yan minimum increase in HP as far as I know kasi fix pa gearing nya..

go synthetic oil nlang and a good spark plugs


pero its up to you if you change it and dont forget to keep the stock parts .

A longer plenum intake manifold will give you more torque. This is the one that actually moves the car. HP is how fast you get that power.

If you get the K&N, make sure wala kang MAF sensor. I heard the oil may damage it pero not sure on your specific car.

The spacers to increase the length of the intake manifold are costly. Thermoplastic, and around 6000 pesos. I don't have the contact for the person on me, but I can get it if anyone wants one fabricated (I'm thinking of doing this).

Thermoplastic spacers increase hp marginally by making the intake run cooler, but give about 3-5 ft lbs more torque because of the increased runner length.

But, as I said, they're very expensive for such a marginal mod. And there are no vendors here. You either have to order them from the US (and I don't think they have the 1.6 engine there) or have them fabricated here.

A cold air intake will also increase torque, actually, because the long tube has the same effect. Technically, it wouldn't produce as much hp as a regular short tube and cone (there are some dyno tests that suggest this), but it gives more power in the real world because of the much lower temperature. But like I said... it's dangerous in wet conditions unless you have a bypass valve (and dangerous in floods even if you do have the valve), and the bypass is expensive.

Personally? I'd just sell the car and buy a manual. I hate automatics. But most of us learn to love the car we drive, and if you want to modify, go ahead. I went through that with the old Sentra AT, too.

thanks to all your advice guys. where could i possibly get a longer plenum intake manifold? any recommendations..... thanks.

My dad got a Skunk2 for his SiR here in Inline4 (www.inline4.com) malapit lang sa amin yung store nila. It's also near Super Auto Bacs. The thermoplastic spacer thingie he also got, makapal nga. Btw I'm based in the US so aftermarket parts are available. Not sure if your Lancer has a wide tuning market here though.

Something my dad said about a short ram intake vs the longer one, the air fuel ratio changed when he shortened the intake (we got some tubing for it, parang plug and play lang). He routed the air filter sa ilalim ng passenger fender on the Civic para direct cold air via the bumper vent. Kung umuulan, he just removes the extension in the engine and installs his second filter on it. The AFR meter suggested something changed, I forgot exactly. I think it's to the effect that the short ram intake had a higher value?

Hmmm... maybe it's the distance of the MAF from the engine? Ah... okay, I get it... on some cars, having an open cone filter right in front of the MAF can mess with MAF readings... by using a CAI, he placed it far enough from the MAF that the MAF was able to work properly.

Oops... my bad, the Honda uses a MAP, not a MAF... but the effect is probably similar. Too much air, too close to the sensor, makes the readings irregular.

It's very easy to get shorter intake plenums for Hondas, as Honda B16s can use Type-R or various aftermarket intake plenums... for the Mitsubishi 1.6, tough luck. The best you can do is thermoplastic spacers. Look on outlawengineering.com , but I doubt they'll have your engine.

You can call Nollie (0910) 785-1240 of PitCrew Performance regarding thermoplastic spacers. He doesn't make them, but he can give you the number of the guy who does. But be warned... they're expensive.

If I remember, 1cm yung kapal nun. Or something comparable.

Niky, it makes sense about the MAP sensor and his readings. MAP far from filter = too much air = increased AF ratio. MAP near filter = less air (due to filtration) = decreased AF ratio. Or something like that hehe.

sir niky ask ko lang yung case ko. 98 civic lxi auto ko. kinabitan ko ng fujitsubo legalis na chambered muffler. after ikabit napansin ko na lumakas yung hatak. pero medyo gusto ko pa palakasin yung tunog. may nagsabi saken na patanggal ko daw yung resonator na katapat ng handbrake. yun yung mataba. dalawa kasi yun sabi nung nagtatanggal. may isa pa na mas manipis nauuna dun sa mataba. ang tinanggal ko yung mataba pinalitan lang ng pipe. lumakas yung muffler. ganda nga ng tunog actually e. pero napansin kong nawala yung hatak na na-gain ko before tanggalin yung reso. parang bumalik sa stock yung hatak lalo na pag uphill ang takbo. im planning to re-install my resonator. or kung ipatanggal ko nalang yung isa pang resonator? ano magiging effect nun? or ipabalik ko yung matabang reso at patanggal ko yung maliit na reso? ano naman effect nun? suggestions naman mga sir kasi ang gastos ng trial and error at putol ng putol ng pipes e. salamat and more power to you guys..
