I have them in my bone stock g37s coupe and I like them. I wasn't expecting crazy power with only drop in filters.
Mate, I run a K&N in my 2003 Peugeot 206 GTi. Standard style. Off the bat there was no throttle lag (previously I’d have to almost put my foot to the firewall, now I only need my big toe). HP there’s not much difference.
If you are handy buy a K&N air filter if you are keep your car >100000 miles and then you will need a recharging kit at some mileage intervals.
I just spend the $50 on a K&N filter for my cars. Another $20 gets you the kit for cleaning and re-oiling. $70 for a filter and years worth of filter clean/renew cycles.
A K&N cold air filter will not hurt , as long as you are committed to regularly cleaning & oiling the filter.
I also ordered a K&N drop in filter.
the only advantage to the k&n is the reusability. for actual filtration, oem paper filters are better. power differences, on these cars, i dont think you will see any differences unless you are pushing over 325hp
I've been using a K&N for a few weeks. I haven't noticed any power gains, but the throttle response feels slightly quicker (this could be in my head, but who cares, I'm happy). No difference in fuel economy.
Welp never buying K&N air filters again.
Air filter, I'd stay far far away from K&N, more flow = more dirt getting in and oil could mess up the MAF. Also, you are not going to gain anything.
