Figured I would start this thread since no one else has yet.
I've owned many air intake kits in my past vehicles, I've always ran either a K&N replacement filter or intake kit in all of my previous cars. I liked the sound that the intakes would give off with moderate to max acceleration.
But, I now have a Mazda5. Not to say I shouldn't enjoy it, but I feel like perhaps its not worth the trouble? I had a friend with a 06 Mazda3, he had a short ram intake and he had issues with the Check Engine Light coming on (had something to do with the MAF I think), and I've read that a couple ppl here as well with their Mazda5s are having similar issues.
Sure you might gain a little power, enjoy the sound of the engine more, but at what cost?
I read that K&N replacement filters do not filter as much dirt and they produce very little gains if any. I don't think I want to consider an intake for this car as there are just too many ppl with issues.
I plan on owning this car for a long time, at least 7+ years and I want it to last and run well with regular maintenance and good all round care.
I think for myself, I would consider a K&N drop in replacement filter as they last long and will pay for itself after 2-3 OEM/paper filter changes, but I don't want to put it in if it will degrade the internal engine components from an increase of dirt entering the engine.
I'd like to hear what your opinion is on this, experiences with the K&N drop in filters and with intake kits.
For reference, the K&N drop in replacement filter part # is 33-2293.
