Celica Forums General Discussion Exterior Intake Recommendation

Sup All, im planinng on getting a TRD exhaust
Whats a good cold air intake i should get? thanks

cai's really won't improve your power very much (about 2-4 horses for a straight bolt-on on a STOCK celica--your exhaust should raise these figures up). the most important factor is seeing that the intake is cnc mandrel bent (smoother bends = better air flow) as far as this goes, all cais that are cnc mandrel bent will give more or less the same power figures.

that said, i prefer the injen cai because of its chrome finish. (style IS important..especially when thats the only real difference)

also, i've heard the heat shield makes hydrolock less likely.

AEM or Injen...they're relatively the same. just look at pics of both installed and decide what you like best.

aem: also available in red, polished, and brushed aluminum (whatever you call it...plain metal looking lol)

and injen

you might also want to take a look at shortrams...the power difference is minimal and hydrolock is virtually eliminated..not to mention the install is easier

injen and rmm are basically the two main competitors..but blitz also makes one.

AEM for more low end power, and INjen for high end.

actually, both are geared more towards high end power...as most bolt-ons are.

as a rule of thumb: a bolt on will decrease your initial torque, but make up for it + some on the higher end.

the dyno's that i've seen say that AEM provides more low end and less high end than Injen.

get injen with the injen water shield, ive got that and the TRD exhaust, its a realy good combo especially if your going to get headers

sorry, i misunderstood what he said. i thought he was saying aem provides low end while injen provides high end. so what i said was they both produce more on the high end and they both lose on the low end (i'm pretty sure). whether which one produces lower low end and which one produces higher high end...i'm not aware of but i'll take your word that aem is better low and injen is better high

Injen

technically its a heatshield..but it can also act as a water shield and your right about the exhaust & headers...the more restrictions you take out of your exhaust components, the better your other engine mods will perform, and vice-versa.

it's both. Injen Heat/Splash guard

aem or injen

would there be any power/hp loss with a heatshield on comparing without a heatshield for an injen?

i think i remember reading in import tuner magazine that the injen cai (although it may have been injen shortram) lost as much as 1 or 2 horses (a lot considerring they don't give good gains to begin with) w/out the heatshield.

No, if its short ram it would prolly increas power a tiny tiny tiny bit, and if its CAI then it will do thothing but protect against hydro lock

wow, thats a lot

if this were true...then i doubt injen would even sell a heatshield with it. why would you increase cost for nothing?

injen

thanks a lot guys you are all great help, one last question.. soo how much would headers trd exhaust and injen cost?

injen cai will run you about $200 in most places

a trial header will cost around $800 but a lot of that is becasue you have to pay shipping from japan (wait on this though--dc motorsports is supposed to come out with a header very soon...and it should cost around $500 maybe..guesstimate)

and trd exhaust will cost around $600 unless your going with the trd kazuma (race only, street illegal) which is about $400

alright cool

One question on the hydro lock thing, any ideas on where the water comes from, wheel well or does it get blown in from the front? And if it only from really deep puddles those must be pretty freakin deep, eh?

you gotta actually submerge it, correct me if im wrong but i dont think light mist of water will kill your engine, i think its suckin up water like it was 3 in. of air flow

as gjgts said (1 post up), you pretty much have to submerge it. this can be from a deep puddle, but it can also be from a relatively shallow puddle if its long enough (or if you hit many in a row). if the water thrown up from your wheels is "thick" enough, this can cause hydrolock.

hydrolock is NOT common though. if it does, it is usually from driver error. it's pretty hard to experience hydrolock with a cai...just pay attention and slow it down when the roads are wet
