Hate to dig at an older thread, but I'm assuming the general consensus is that "IF" you purchase the Corksport SRI, you need to get the airbox to keep the temps the same as stock.

Yeah more or less. Depends on what you want from the car. Using just the SRI you get a wide variation in intake temps and fairly high temperature spikes. The box tends to keep the IATs more stable.

K&N 69 Typhoon CAI here.. it's an aluminum SRI with a K&N cone filter and a heat shield with a rubber/foam outer edge that seals things up with the hood down. Adds a nice growl to the engine.

That is what I figured. If I buy the SRI shortly, I would buy the box.

Thanks CK, the K&N is cheaper than the Corksport combo. Just wondering if the IAT issues are any better.

The additional tinkering possibilities are far better with the CS box....:smile2:



I saw that post earlier. Pretty neat thinking to place heat insulation wrap on the box.

The plan of the car is just to make it a little quicker, sound better and make me feel good about doing little mods on my Mazda 3. I have been out of the car mod scene for years...
This is my new DD, so I don't have lofty plans for it. Intake, Extreme Performance exhaust and rear sway bar and that's probably it.

The proverbial "famous last words".....:laugh2:

If its more power you are looking for, get it tuned. All the other bolt-ons don't do much with out it, and a tune is the only way to make actual significant power gains.

The CS box works well if you have the 2.0L engine. Its air inlet is 30% or so smaller than the OEM CAI air inlet that comes with the 2.5L engines though.

That's why I got the K&N instead of going with the CS SRI and cold air box.

My car has never overheated and my temp ranges were good when I did data logs for my OV Tune. Never had a CEL with it either..been using it for almost 2 years now.

Thanks, I actually went ahead and picked up the K&N. It came with a $50 rebate gift card.

After install, it has a significant growl. I was pleasantly surprised.

Yeah. It gives the car some added personality and looks good under the hood. Add in an axle-back exhaust and your Mazda will sound even meaner.. in a good way.

I have the Ultimate Racing Axle-Back with the steel rolled tips. Sounds great without being overly obnoxious or droning on the highway...no crazy vibrations from it either.

I was actually going to search the forum for anyone who had the K&N intake and the UR Axle-Back. I don't want it to sound too annoying, but I definitely want it to sound tougher. Have you ever posted any sound clips on YouTube or on the forum with the K&N intake and UR exhaust? I found a few videos, and one owner has the muffler-delete option. Thanks!

No, I have not. My 2 year old son is able to sleep while I'm driving with no problems, if that helps at all.

My wife doesn't even complain. I believe Racing Beat has the least loud performance exhaust for our car. The people that have one love it.

I'm looking to improve the sound of my 2017 manual 2.5 Mazda3 sedan (basic GT trim in Canada, not sure what's the equivalent in the USA). I'm pretty set on ordering the CS axle-back exhaust, which based on what I've read will give it a good low-rpm sound. I'm still not decided on whether the CS SRI is worth ordering to get some growl in the higher RPMs, as it sounds like I would need to get the cold-air box as well... How much would it actually improve the sound, given that I will have the axle-back already? Shipping to Canada is also a factor - it not cheap and the price difference between shipping 2 products together vs. at separate times is significant.
