I purchased a Samco Hose, but sold it to Mr. Sparky because I couldn't get it to fit exactly with my Ebay cone filter. I will be remedying that this next go-around , so I will be purchasing the Samco...again...for my next round of mods. The inside certainly looks bigger/smoother than the stock intake pipe.

Also, on the Dejon, I purchased one of those a few years back. It wasn't deburred on the inside and fitment wasn't perfect either. However, things can change since that was over 2 years ago.

 

The Samco has a smooth transition where the OEM has the bellows, after the DV both look the same.
The silicone hose keeps the MAF isolated from vibrations. I don't know if a hard pipe amplifies the effect of loud noises( open exhaust cars beside you, rattle boxes with loud bass) making the engine stumble.

I had to cut 1/2" from the turbo side to make it fit with the stock air box. It fits perfect now.

 

What would you say about the HKS suction intake, should i revert back to my oem?? its funny i thought i felt more kick with the stock..seemed more pressurized...as oppose to the "hollow" feel.(if you know what i mean).

please advise...

 

do not get the samco i had nothing but problems with the silcone,it ripes around the blowoff valve when u try to tighten it,get the hks hard piping much better off in the long run...i even had idling problems with it,
once i changed it everything felt better from idle to wot










this was perrin but u get the idea this was 6 months later

 

ive run the samco hose on my car & my G/F's IX for over a year with no problems, holding up fine, i cant say anything about perrin as they usually make good stuff but i wouldnt group all flexible intake tubes as bad just cause the perrin one failed. perrin makes many products, samco makes hoses.

perhaps they did not use enough plies of reinforcment or thick enough silicone

also, youll have a hard time finding any metal intake pipe with as smooth of a transition as the silicone, which is pretty important considering the diffrence in size of MAF & turbo inlet


for the OP, yes, the perrin/samco pipe will affect MAF load readings

 

maybe but my hks fit better then the silcone,this silcone would hit my lower raditor hose,my friend has the samco on his to and he had problems with the clamps riping it,but whatever he wants to do just posting up my exprience with silcone hard piping is always better....

 

I've run Samco on many cars and never had problems...overtightening will cause problems

 

Regular perforated worm drive clamps are BAD with silicone couplers. There are "lined" clamps and clamps that use an external threaded tightener so that the silicone coupler does not extrude through an improperly tightened clamp.

Get the right clamps...you will probably have a better experience.

 

The HKS suction is a hard pipe inlet, if I'm not mistaken --- which is a great upgrade as long as you're tuned for the extra airflow. Also, some people say that the stock hose was "accordioned" to baffle turbulent airflow and improve idle quality over smooth pipe inlets, but that may not prove itself to be true in every case. I know what you mean about that "hollow" feeling. I always chalked it up to the greater inner diameter of the hardpipe resulting in slightly lower initial air velocities (until the turbo spools, that is).

Then again, my theory may be stupid.

 

On my 03 I ran the OBX silicon turbo intake pipe. It fit perfectly and held up just fine. I purchased it thinking the stock piece with "ripples" was a restriction but my airflow didn't change after the swap. I also had hoped the intake would be louder but it wasn't. I highly doubt you are outflowing the stock intake pipe with the stock turbo.

My review... its pretty... but it didn't make my car go any faster. It didn't change my MAF readings or Airflow.

This was with the stock intake box which is what I stand by. Conical filters change MAF readings. This is especially true if you pull the air dam off because the filter will see varying airflows at different speeds.

 

Not stupid at all. Ive always thought OEM parts were the best tested and have a purpose so thats what I was going on(along with the fact that it "felt" better). Did you in fact increase airflow via EcuFLASH tables for your inlet pipe(HKS Suction Inlet(which is a hard chromey pipe))? I would love to take a look at that is available.


Thanks in Advance....

 

Well, I'm a mail-in flash kinda guy, but that's a valid question for the gallery . . .

Anyone out there have Ecuflash tables for inlet flow rates?

???
