I have a golden rule for Modifications.
Always revert back to original equipment when taking it for a warranty claim. *
THAT is very sound advice there...however you don't need to as it was pointed out so long as the modification does not directly harm the car or cause the problem BUT if in doubt, change it back.
I know GM people who swap their chips in their cars back before going in for a cat. problem which was a problem in corvettes (I can't remember the year), the ceramics inside would crumble, in that example the doubt of higher performance i.e. heat from the exhaust "may" cause premature wear. Others didn't but from what I heard they had no problems as it was a recall or TSB or Federal EMI problem....again I don't remember. This is just an example and not a bonified thing I can say happened just that way.
Let us say you went in for a siezed engine...the dealer pulled the car into the shop and this I've seen many a time, you were lax on oil changes, had the ole' jiffy lube filter on it, the cam was covered in sludge, the ports were clogged, the lifters just caked....right off the bat without mod or not there will be pictures taken and you'll be asked for complete oil change records and you better have them all or at least most.
Senario two, same problem, mazda filter, dealer serviced, and K + S or the like cold air intake...and it has been checked over by the dealer, what can be said, NOTHING.
Same thing in example 3 with a bit more tweaking the addition of an el cheapo eBay cold air simulation bypass chip, I hope you know what I mean.....IFFY, that I would take off .... More and more the OBD II will register errors when engine lights come on so I don't PERSONALLY like those cheap ones anyway except on maybe an old MX-6 GT or something before OBD II. If I were inclined to go that way I'd spend the money and do it the way it was meant to be done.
Like the supercharger but crossbow, can you do that??? I know the 2.5L can accomodate the supercharger, the problem with our engine is the space in the compartment. If there is a spot in the boards for this, I have not seen it. Duratec along with VVT and supercharging IMO might not be a good idea...
I'm waiting on the Injen to be perfected....it is pretty darn cold here so I have natural cold air feed for now. I'm headed over to the modifications section to go find some stuff, I got plenty of good points from the gifts I got the wife :)
Merry Christmas to those who celebrate.....
P.S. anyone get any mods for Xmas??? and anyone got a link for an upload for a good pic of a redfire Mazda 6? Mine is filthy, it is snowing and snowed last night while we were out and the salt is all over it(again).
