for a ebay one get the most expensive, which is like 40 wink check out for diameter of pipe. if its not listed ask them. you want 2.5-2.75 at most 3" but 3" you will deff need blue bomber mod (search on ecelica and you will find a million threads on it. ) or go to newcelicaDOTorg and go in installs.

i did a lot of reading on that... and the conclusion that i came to (from the experience of others) is that ebay intakes are just as good, and when you buy AEM, Injen, etc.. your just buying the name.

Also, you're not just buying the name. You're buying tech. support and a warranty, along with carb certification. There are some advantages.

If you're going for show or really like showing your car off, you might want to invest in a name-brand, otherwise get one on eBay and use the rest of that $200 for another mod. An intake is an intake, it just improves airflow to the engine; AEM might have designed it slightly better but I doubt you could tell the difference. Spending $200+ for 1-5hp is not cost-efficient in my book, unless you get sponsors from it. cool

ohboy

An intake is NOT just an intake. Everything comes into play on what part of the power band is affected and by how much. Pipe diameter, bends, maf placement, length of tube, etc ALL have an effect on how well the intake performs.

Take Injen for example. It has a very nicely flowing design. Thus is makes 2-3 whp more than AEM uptop. HOWEVER, its MAF placement is the worst of the three name brands. Thus it loses quite a bit of low end and even runs a risk of throwing a CEL.

AEM has a decent MAF placement. HOWEVER, its got well over the degrees in bends than Injen does, thus high end is lacking. Because of its SOMEWHAT laminar MAF placement and bends, it does retain a large portion of low end power.

Ebay intakes are pretty much low quality gen1 AEMs. I used to have an ebay intake, I got a CEL and bog almost immediately. But like people have said, every car is slightly different.

The absolute key to intakes for our cars is the MAF. Making the best flowing design will be rendered pretty much useless if the ecu doesn't get the correct air flow readings. The MAF gives the absolute best reading when perfectly straight (linear) airflow is provided for it. From what I've typically seen with AEM and Injen is the MAF reads less air than whats actually flowing (more so on the Injen than the AEM). This causes a leaner A/F mixture. Too lean of a mixture causes a CEL and "bog." Running too lean for an extended amount of time causes damage to the combustion chamber and the bottoms of valves.

If you look at the inside of the stock airbox where the MAFS sits, you will notice a set of "fins." The reason behind the design and placement of these fins were to assist in creating linear flow thru the MAF. You will also notice that toyota added a "bell" fitting at the end of the intake tube inside the filter chamber. This also assists in creating a linear and equally distributed airflow thru the MAFS.

There is a formula for achieving perfect linear airflow in relation to pipe diameter. But for the sake of the non physicists on here, we will just say that the longer the straight pipe before the point of the measure, the better linear flow achieved.

With that said, now onto TPR (puts on flamesuit). Science (and the picky-ness of our MAFS) was the founding reasons behind the design of the TPR intake. There was originally two designs I had laid out for the intake. The first would have flowed much better than Injen and provided a slightly better linear airflow thru the MAF (in comparison to the production model), but there was no easy way to mount the pipe to the car frown. So a slightly altered, more installer friendly design was made. The main focus was tuning the MAF environment AROUND the MAFS picky needs. The fins were definately going to have to be used for assistance in creating linear flow (because we don't have very much space to play with). The final result posted amazing results. I managed to come up with a system that had a longer straight pipe before the MAFS while still utilizing the original "fins." Ultimately this created an intake providing the ECU with the best reading out of all the "name brands." The A/F mixture was not much leaner than stock (meaning its still in the engine safe zone). The CEL never came on, and lift seemed to enjoy the better reading (producing some 12-15whp above stock at its engagement!) Peak power rivaled that of Injens producing about 7.5 whp on my car.

So to say spending 200 bux for 5whp is silly. People spend 500+ for that in an exhaust alone. In this game of modding, you gotta pay to play! smile


TPR Intake! - Injens high end with AEM's low end and NO BOGGING!
TPR EXHAUST! - Exhaust made 10.5 whp peak and 32 whp at 6300 on my car!!!

Try to find the seller that ships for 15 dollars. Most of them ship for 20 bux, so in the end your gonna be around 40-50 bux shipped for the intake.

me either! my celi has spent enough time outta commission already. I'll do the Perfect CAI mod on it just to be safe though.

and just to clarify were you referring to the CAI or SRI that ships for 15$?

got an ebay intake.. AEM replica. Works perfect. No bogging whatsoever and no CEL. id say 200+ for injen or aem isn't worth it for those "tech support" or license plate frame stuff.

I ended up Buying one for my 2000 gts and it was amazing, no problems no CEL and it was like 30$, came with everything i needed, then my trans when out and they hooked me up with an 04, yea and since then haven't had anything but problems so I run w/o a Cold air intake now, anyone I've known with an 03/04 with the Electronic Throttle Body has issues, unless its Blue Bombers, I even knew a couple of guys that had AEM and Nothing but issues. GL on your search bro

cr4sh - i dont think they are hard to put on... there shoudl be an install guide in the installs part of the site.

GjGts - where did you get it from or who was the seller (of the one that worked)?
