Are k & n typhoons any good and will they improve the sound?

For years sports car enthusiasts have flocked to Nissan dealerships to get their hands on the infamous line of Z-cars. Since its introduction in 1969, the Nissan series of Z-cars has sold almost 2 million units and holds the record for best selling sports car series of all time.

 

K&N's 69-7078TS High-Flow Intake System for Nissan 370Z and Infiniti G37 3.7L V6 models.

 

Dual silver powder coated aluminum intake tubes increase under-hood appeal.

 

 

For many reasons the Z was forced into hiatus during the late 1990’s. When it resurfaced in late 2002 it wasn’t alone. Nissan Motors, who also builds luxury vehicles branded as Infiniti, created a line of Infiniti cars based on the Z platform. The now legendary G coupe and sedan were born out of this relationship.

 

The 2009, 2010, 2011 and 2012 Nissan 370z and 2008 through 2012 Infiniti G37 are well-engineered machines. However, K&N engineers are constantly in pursuit of more power. After looking under the hood, K&N engineers knew that with their expertise these cars were capable of more. Much consideration was put into the design of part number 69-7078TS for the 2009-2012 Nissan 370Z and 2008-2012 Infiniti G37 models with a 3.7L V6 engine.

 

The stock intake tract uses a dual intake set up fed by dual air boxes and air filters. K&N intake 69-7078TS replaces the stock pieces with twin powder coated mandrel-bent aluminum intake tubes and dual K&N High-Flow Air Filtersâ„¢ for improved air delivery. 69-7078TS incorporates two unique heat shields isolating the dual air filters from the warm air under the hood. This intake system provides improved performance and attractive silver powder coated aluminum Intake tubes to match the color of the engine bay.

 

 

Dyno chart for a 2009 Nissan 370Z 3.7L V6 engine.

The result of this hard work and enthusiasm for performance is estimated at over 14 horsepower at the wheels. K&N’s Research and Development Department tested a 2009 Nissan 370Z with a 3.7L V6 engine on our in-house dynamometer. Results showed horsepower increases throughout the RPM range with a shocking peak horsepower gain of an estimated 14.2 horsepower @ 5,600 RPM! Equally impressive is the estimated 13.34 lb-ft of torque this car picked up at 5,600 RPM.

 

 

2009 Infiniti G37 Coupe.

This air intake system uses two conical shaped, High-Flow Air Filters. RU-4960XD captures harmful particles, flows more air, and provides long service life. This K&N air filter performs for up to 100,000 miles before service is required, depending on driving conditions.

 

In addition, K&N offers a RX-4990DK Drycharger® filter wrap that can be used in conjunction with part number 69-7078TS. Drycharger® filter wraps are durable pre-filters that are designed to filter large dirt particles and thus extend the time before the main air filter needs to be cleaned. These wraps can also repel water but add little restriction to the airflow of your filter. The wraps specifically designed for this intake filter are available in black, blue, red, and yellow.

 

69-7078TS is a complete system which takes about 90 minutes or less to install with common hand tools. It uses stock mounting points, requires no drilling, and is covered by the K&N Million Mile Limited Warranty®.

Are they worth the money?

 

These kits seem available from not much over 300 quid.

 

Usually I've found with past cars putting a K&N kit, whilst it makes little performance difference, it does make the throttle a bit more responsive.

I've always thought K & N are K & Poo! when ever I have bought their air filters (albeit on 2 occasions) all I ever noticed was the car used more petrol. Pipercross on the other hand seem to make a difference from my experience, if not made a great noise.

Installed it today.

 

The noise it very smile inducing at higher revs, but barely noticable low down - exactly as wanted.

 

Throttle seems slightly more responsive, as you'd expect. Any power recovered from this is barely noticable.

I fitted my set yesterday.

And agree the throttle response has really improved.

The sound is better a bit throatier especially up the rev band. Also changing down with synchro on sounds much better. ;)

I've had this in for 10 days now.

 

Key points.

  • Build quality of the kit is excellent
  • Look of the kit is excellent
  • Very easy to fit, no hassle at all with anything, everything just clips/bolts/slots straight in. Some minor cutting of the rubber trim required, but very easy.
  • Kit sounds pretty much like OEM during regular driving - no induction drone
  • However, let the right foot go and the sound in the cockpit is very nice. The sound really comes alive after 5k revs.
  • Throttle response has slightly improved
  • Fuel economy has slightly improved

In all, you probably can do the same improvements for well under the £350 this kit costs but... it is a £35k car, the kit is built for the car, and when installed looks like the job has been done properly. It's hassle free, instructions are perfectly clear and even a novice could have this fitted in 90 minutes.

Throttle response better lower down the revs? eg setting off!!!!

 

I wouldn't say so no.

 

I find it more in the mid revs and over taking range. However it is only a very slight increase, that admittedly could be a placebo effect with the sound increase.

As above but I can't vouch for the fuel economy improving even if it's slight. Because my right foot loves the much improved sound it make when pressing on the go pedal :lol:

 

Highly recommend the typhoon kits though other makes are available. But I'm very happy with the purchase. :teeth:

I do quite a bit of distance travel, and I always do it with the cruise control set to 77mph, using my GPS.

 

Usually the run I do averages around 28-29, but I was over 30 last time I did it.

 

However this is negated by the B Road running, which has certainly seen a drop in fuel economy for the exact same reasons lol.

Above comments ^^^ all sounds very positive think this mod may have to be moved up my to do list, due a p3 soon so reckon these could be fitted instead of oem air filters :) better get on the overtime at work though as they're not cheap

Have to agree it seems a reasonable price for a dedicated kit, a good looking mod, the induction noise is a bonus and as I always say I love a bit of engine bay bling so sounds like win win :) keep the reviews coming as lesser experienced zed owners ( like me ) take great interest in posts like these ðŸ‘

I read on the American forums for the 370z's the short ram intakes reduce power? or is that in the American 20-30 degrees climate? Do you need a remap to improve the cars ability to accept the larger intakes or again is this due to the American cars being tuned to run on combustible sludge?
