Everyone,
I have a 2003 Tundra Access Cab SR5 V8 4x4. I have heard and read quite a bit about both the K&N FIPK and the Volant "cold box" (cold air intake mod). Can anyone tell me whether either of these was worth the money spent? and did you modify your exhaust/headers before you used either of these products?
I still have two kids to put through college so I am minding my modification Ps and Qs. Thanks...

I have the fipk , and I didn't notice much increase . I have learned that they do not recommend it for 02 1/2 or 03 due to a lean fuel response. The software cant compensate for the increased flow.

get the trd supercharger that would be sweet. im just dreaming have fun with your intake

i wish trd had one for the 3.0

I wouldn't mind the supercharger if it weren't $3G, but worse than that is that after you install it you have to run 92 octane or above. I think I will stick to getting the TRD exhaust from head to tail, then add a cold box to the intake.

We sell the FIPK system at my dealership but won't sell it to customers it leans out the system to fast and decreases horspower. This is with or without the SC.

I have the K&N Fipk on my 2000 V8 Tundra, and I noticed a huge difference. Is there any problems with running that system on this year of truck.

TOR

I wouldn't run it on any of the Tundras from 2000 and up. This is per our director of service and parts here.

For what reasons would you not run the FIPK on a 2000 and up Tundra?

TOR

Notice my previous comments pertaining to leaning the engine out. This is the whole reason we don't, symptoms start with loss of compression and then a new head which is very expensive.

TOR,
That makes sense. Toyota has done a very good job of getting every bit of power out of the stock engine with changes to the engine control module program.
How about that supercharger? will it really require the use of high octane gasoline? With such a large increase in HP and torque will the Toyota A/T and differential handle the added stress? I have heard some folks have had to replace parts of the drive train prematurely. Just curious.

TOR

Well to answer your question it does require high octane. If you don't use the high octane you will develop a ping or rattle. This is a proven fact, everyone including myself at the dealership that run the SC all use premium.
As for the differential and the AT, I haven't had any problems at all with mine. TRD wouldn't manufacture something that would void the powertrain warranties on their vehicles. The SCs have their problems just like anything else however I love the peformance and think the cons really out weigh the pros.

TOR,
Thanks for responding. Did you really mean "the cons out weigh the pros" or did you mean this in the reverse? If this is what you meant what other cons are their?

TOR

Yeah strike that and reverse it. Definitely go with the SC if you can, I promise you will like it!
