m7 Drop in Filter
 

Now I've been doing alot of research and looks like once my brake-in is finish I'd go with the HPS Tube and drop in.
Now as far as Drop-in HKS, K&N, and Now I learned about M7....
HKS is a no brain-er,
but K&N vs M7? anyone try out this company? Products are designed and manufactured from Japan.
And surprisingly Cheaper than KN drop in... Hm
M7WorldShop
Opinions?

seems like over priced filters lol

id go with K&N

I cringe when I see this. Sorry.

Its $10 cheaper then K&N......is it really worth the $10 to buy something that may not do anything compared to guaranteed gains? Plus is M7 shipping from Japan? How much is shipping cost and how long would it take you to receive them?

K&N drop ins. Done.

370Z / G37 K&N Drop In Filters

They have Warehouses here in the US.
Just curious if anyone used them + dyno results?. Or even heard of "M7"

M7 is well known, not for drop in filters though

Why? :stirthepot:

M7 makes nice looking products, but for the price? Go with something that is reputable and proven.

M7 heat shields are sick...not worth the money though.

Somethings you might want to find out; whether its a dry or oiled type filter, this way you know the proper way of cleaning/recharging it. OR if it's simply a disposable type, where once it's dirty, you replace them with brand new ones

Go with K&N. Extra cost is minimal, maintenance is known, and the benefits are proven.
