Which SRI?

Injen

or Fujita?

I didn't even know K&N made one until now.

This is for the 1.8 Corolla S btw.

If you really want the SRI then get the K&N. good brand, you know you can trust it.
If you end up wanting a CAI then I say get the Injen. Injen and Fujita make CSI's for our car, K&N doesn't.

I'm getting the Injen CAI for my car. I just prefer CAI.

Weapon R has a SRI for the S as well.

The Injen may gives you a little more gain over the others, it is a CAI. The only disadvantage of CAI is hydro-locking (sucking in water from the intake to the engine). To be honest with you, it rarely happens, unless you area is flooded with water....haha.

takeda makes a nice intake for the 10th gen 1.8l. It looks like it even comes with a heat shield that is comparable with the k&n but at a lower price



i personally went with the FUJITA SRI. They also make a CAI if you are interseted. The reason I went with the FUJITA instead of the other brands is just because of cost. I know the FUJITA is a quality product and its also the cheapest. I paid less that $170 for mine.

If you look at the k&n, the fujita, the weapon-r, the takeda etc etc, they all look the same. the only differences are like the filter, the couplings and some intakes come with a heat shield. those minor differences will mean only a fraction of a hp difference between the intakes, if any.

Thanks everyone for your help. I heard somewhere that you don't feel too much gain from the weapon r?

oh and what site did you buy your fujita sri from?

[ej063090]

ebay has them for $185 fujita http://cgi.ebay.com/ebaymotors/ws/eB...m=270483836605 i best offered it for $165

actually you won't feel that much gain with just an intake on a N/A car, no matter what brand it is, especially on an auto

let me know, where you got that info about the weapon r please...

as an engineering student, im debating if those concentric tubes could induce a better airflow into the engine, wich I doubt with the regular short ram, but with the "ram kit II" that they offer, I do believe some better gains are available from weapon r'. Depending on the filter, if the filter is good as they claim on their possibly rigged tests, the actual air flow should be increased with the "ram kit II" when your car is moving. Without it, theres praticly no way the there would be an increased air flow compared to a same size SRI.

The pressure/vacuum at each end is still the same for the inner and outter tube. The only difference there is, is the friction on the inner tuber is slightly less because of less Area of contact in the tube, wich in reality isnt big of a diffrence. Also, the inner pipe also reduce the available volume inside that 3in pipe, thus, creating a restriction compared to a regular 3in.

any opinion/thoughs?

Or you could just remove all the snorkel like a lot of us did FOR FREE. Add a high performance air filter and get 99% of an SRI for almost no cost.

I went this route... And when I go in for Maintenance, I put the snorkel back in. It take about 5 Minutes to do, and a simple Plastic X-Mas Tree Clip to replace the one you will break during the uninstall.

? lol, I'm such a noob...

I've had the modified factory box, and i currently have the Fujita SRI

the power gains between the two are minimal. my butt dyno (highly unreliable) felt no difference between the two.

the fujita is shinier, and takes up ALOT less space than the factory box.

the fujita costs more. but did i mention it was shiny?

the cone filter also has more surface area than the factory flat filter. this means the filter will last longer before being cleaned/replaced.

but i guess the main reason I went with the fujita was to make room for other things. the factory box and resonator just takes up too much space.

All of them look pretty cool, K&N says 6-7 hp gain at 5.4krpm but is really expensive, ouch. Lol.

Cold air sounds like it would do the most but I don't want to take out a foglight just for it. I guess I'll just go with whichever I have the money for and suits me best. I don't know how to mod the factory box, that sounds like it would do a sufficient job I guess for now if I knew how to do it.

Realistically, those claims mean 1 or 2 hp tops.

Do a seach, I believe someone wrote up a DIY on how to modify the factory airbox in one thread.
