Need reccomendations for *best* CAI or SRI (I4) - Toyota Nation Forum : Toyota Car and Truck Forums

Arright then. gen 4 5s-fe I4

I serached "CAI" and did learn some info.

Quite honestly, I am really new to all the performance mods so i got a long way to go. Anyway, I read on one of the threads that a CAI is better than a SRI., Some may care to differ.

But i feel that having colder air is the way to go. Well, I also read that having a CAI is still fine even if I don't have a Catback exhaust system or header?

Well my goal is to increase my pickup speed and acceleration as much as possible. If the CAI helps on mileage that'd be a plus too.

I don't got much $$$ for a TB or Supercharger and I don't think I can find one right now anyway for a Gen4 I4.

what can I do to maximixe my pickup speed and acceleration ???

well first of all i have a gen 4 5sfe i4 also, i bought the injen intake sri and acceleration increased a lil and the sound is incredible, i plan to extend it to a cai. If you were planing to buy a cai you cant cause they dont sell them. The only way to go is to build your own. Intakes dont really do nething no matter what you have but i like to bring attraction to my cars engine so i did it anyways. other than that i would do a tune up " new filter or clean filter if its reusable, oil change, new spark plugs" when you keep your car in tip top shape thats when it can perform the best. thats your best bet if your not tryin to spend much money.

i think CAI will give you some hp but not much (JUST ABIT) with SRI you tend to lose power when the engine gets abit too hot.

nitrous.

He said the cheapest way to get performance. i dont think he meant spending 700 dollars on nitrous. Although if you want true performance for the cheapest hp per dollar nitrous is the key.

Well, I'm not that enthusiastic that I wanna go nitrous.
I just want my stock acceleration to increase and be smoother with a CAI or SRI mod, or any other not too expensive performance upgrades.

Right now when i accelerate from, the car revs higher than its porportional speed in my opinions. I wanna firm, good, smooth pick up.

I'll probably clean the throttle body to help too.

Is their a so called "best" or good reputation- having TB cleaner or they about all the same.

Should I also do fuelinjector cleaner? Which brands yield good results?

cheap and performance cant be had in a sentence.

auto - normal (Stall). manual - worn clutch.

unless you filter the pcb dont bother.

say what?

waste of money.

(and also for teh last 3 lines, seafoam)

A CAI does not help until higher RPMs. A SRI works much better at low RPMs. Go to Injen.com and check out the dyno sheets. If youwant low end power (for better milage) get the SRI. I have a K&N dropin filter and a flowmaster exaust and I get 3 more mpg when I take it easy than I did before. Be sure to disconnect your battery if you change anything, you ahve to reset the ECU or it will run crappy.

Good luck!

So should I Go CAI or SRI if i want better pick-up acceleration?

just get a clean filter panel and remove then intake resonator in the fender. this gives you a path of almsot coldish air (from teh front side vent in teh bumper to the opening from where the resonator came out.

theres 2 bolts on it, should take 10 minutes at most with a screwdriver and socket.

mystickid · 10-13-2005, 08:21 AM

I think I'll go with a regular replacement K&N filter for my camry. Once mechanic told me that I'll lose MPG with a CAI or SRI. So I'll stick to to replacing the stock with a K&N.

Are there any drawbacks or disadvantages of removing the intake resonator in the fender???

throwback · 10-13-2005, 08:58 AM

if you want fast performance then you cant be worried about that mpg bullshit . look either you want performance or you want to be like a grandma who is always worried bout the mpg. there no way that you can get fast performance without lessening your mpg.

mystickid · 10-13-2005, 09:46 AM

But will a quality Intake CAI/SRI give me a noticeable speed pickup increase?

There is a trade off between the two MPG VS. speed in air filters. but if the speed increase is actually noticeable than it'll be fine if not then I'll looks towards saving on mpg..

I just want the better of the two

Dark-LE · 10-13-2005, 12:09 PM

Okay, i started off with a Weapon R SRI for my Gen 4 5s. It was... LOUD, and when i started to drive id see SOME gains. But once the engine bay got hot, id get NOTHING from launch, less even. But then i did a ghetto SRI to CAI extension (basically some dryer hose) into the fender, i noticed more mid to high end pickup. My MPG did drop... i dont know what i was getting before, but now im getting from 20 to 24 mpg. Which is HORRIBLE for a camry! I might do seafoam, i might not.

But if you want a better launch... Supercharger. There really is no way to get yourself a better launch for cheap. The SRI and CAI are all well and good for making you think your car is faster (its all the noise) but its not. So if you dont put some money into it, for more than just an intake, like headers exhaust and intake, then dont bother. Unfortunatly, most 4 cyl camrys are not that fast. The best way to get them to be more powerful is forced induction, or a 3sgte swap.
