A note of caution to those think that Mazdaspeed products will necessarily preserve your warranty:

http://www.mazdas247.com/forum/showthread.php?t=123662882.

The dealer told this guy that a bent rod can be caused by a cumulative increase in water in the cylinder due to the MS-CAI. I guess you could call this "creeping hydrolock".

I'll say it again, the green warranty is a replacement warranty on the CAI itself (that doesn't even include labor) if it should happen to fail. How a CAI could fail, I can't imagine. Even after a full hydrolock it would work just fine if the engine wasn't screwed. Who knows, maybe his CAI was under the orange non-warranty. Anyway, this should be cold comfort to Mazdaspeed accessory buyers who don't have the parts installed prior to taking possession. That's the only situation I've ever seen a written statement that they are warranted as part of the general warranty.

Maybe a very friendly dealer can protect you, but odds are probably way against you if a major repair is involved, such as the new engine needed in this situation. Of course, the odds of ever needing a new engine due to bent rods are probably pretty low.

Quick everyone sell your MS-CAI !!!!!!!!

I think i should make a new name so i can try to upset people on a product, its really easy to do and i dont have to support any of my claims, even if its impossible by laws of physics

water in the cylinder due to creeping hydro-lock... that is a first for me. He has major problems unrelated to that silly intake. Sounds more like a blown head gasket that is allowing moisture to CREEP in when cool. One tiny tiny crack can really jack up the internal integrity... especially in such high pressure of the MZR. I'm not knocking the claim, but there are other, more feasible causes than an intake. It is still possible though.

I should submerge my intake in a bucket of water and start it to find out how fast I can shut down my engine. I'm willing to bet at least 2 bucks that it makes it through ok.

Hahaha!

I read that whole thread, and I don't buy that story... creeping hydrolock is a bogus theory. He may have blown a head gasket and the dealer is just trying to weasel out of replacing the motor under warranty.

I was told it can happen as a cummulative thing and that eventually one or more of the rods bend as water accumulates in the cylinder causing pressure.

Water accumulates in the cylinder???
That is totally hilarious.

Back in the old days, we used water injection on carbureted turbo motors.

if i took the head off and ran the car in a rainstorm it might happen. that is one severe cop-out or a really tall tale. my left leg is already a little longer that the right one from this thread.

Back in the day? we still do

.

Water into the intake tract isn't that bad in contolled doses. Small amounts of water creeping up the intake would give the pistons a good cleaning

.

Water/Alky injection is a great way to squeeze a few more PSI out on the street without race gas.

Water is only going to do damage to major components when the amount of water ingested exceeds the volume of the combustion chamber at TDC.

It hurt to watch that... That Honda put up a great fight. The idiot who was doing that is probably going to die young!

This part caught my attention...

My dealer brought this point up to me last night, which sealed the deal for them installing the CAI PRIOR to me picking up the car next week. Peace of mind I guess.

THat is such bullshit! I had a Ford 150 that was leaking coolant into one of the cylinders. I would start that that thing up andit would smoke like a freight train for 10 mins until it burned all the water/coolant off then run just Fine. You would see some sort of smoke if something was leaking inside the cyinders slowly. Nothing can creep inside an engine when its super hot. It would evaporate before any damage was done. That is called a Dealer trying to pull a fast one.

The dealer bills Mazda. Warranties are not at dealer's expense. Some dealer's love those as they can bill the manufacturer for labor and make a profit servicing.

You miss the point, Matt. Unless this guy is completely making this up, at least one dealer tried to blame bent rods on a Mazdaspeed CAI. The theory is absurd, but they still tried to float it. I changed the title of this post to make it clear that I think it's BS.

I'll say it yet again: unless you have it in writing from Mazda that your post-delivery MS-accessory is covered under you general warranty, it ain't. A friendly dealer can help you keep coverage, an unfriendly dealer can make it much harder to keep coverage, and Mazda can trump either. The bigger the potential bill, the more likely either the dealer or Mazda will try to wiggle out.

Thanks for ending this idiotic dealer's argument. Of course that has to be true.

i love the internet, to hydrolock a car it needs like a cup of water in the cylinder and its not a MS thing any CAI can do it if you drive like an idiot in the massive rain. Nobody will cover hydrolock it does not matter who makes your intake.

hey tonkin... is your store in the same location in as the acura store? they reason I ask is that my company does business with the acura store via our auction site, and thought it was a nice coincidence.

sorry to go off-topic here.

Actually, we can measure this, can't we? Based on Shark77's guideline, you need more water than the volume of the combustion chamber at TDC.

So, (2.3L) / (4 cylinders) = (.575 liters per cylinder)
(.575 liters per cylinder) / (9.5 compression ratio) = (.061 liters TDC Volume)

So, you need .061 liters of solid water to fill the compression chamber.

File this under usless information.
