🚀 K&N Engine Air Filter: Premium, High Performance, Washable Replacement Filter for Saab/Vauxhall (2002-2011): 9-3, 9-3 Series II, Signum (33-2337) Review

This filter is as easy to install as any factory air filter. This allows the engine to breathe better, resulting in better performance and better fuel economy. Since it is a permanent filter that is easy to clean (recommended after 50,000 km), this filter is worth the money. It pays for itself in fuel savings and filter changes.

I have been planning to order for a long time. I have a 2004 Saab 9-3 Aero with manual transmission. That's almost 50,000 km. I felt his power was a little lacking. I knew about this product and read what it has to offer. I will definitely say it delivers. I've noticed an increase in fuel economy of around 5% and clear instant mid-throttle power. It doesn't cure lag. Not a miracle worker, but opens up the main powerband.

Great filter, durable, lightweight, thin and light improves performance and sound. up also cranks the turbo slightly after it stutters on the way down. Doesn't sound like a BOV, doesn't give you an insane HP boost BUT much better than stock and much more affordable than the BSROptiflow system.

Ideal for Saab 9-3 2005 with 2.0 turbo engine. The product was well packaged (the filter came in a sealed plastic bag in the box which kept out the initial oil and dirt). Ideal for air box. Tip: Vacuum before you start so you can vacuum the airbox as soon as it opens. I have noticed a slight increase in fuel mileage, this may be due to increased K&N mileage because the old stock filter was dirty, or a combination of both. the acquisition costs of a conventional Saab air filter, the investment…

Bought for my 2005 Saab 9-3 Linear. The replacement took less than 5 minutes using a T25 torx bit to unscrew the cap and a flathead screwdriver to pry off the air hose. The K&N filter fits perfectly. It's around 3-4 times more expensive than a standard filter, but it's washable and reusable, so it's worth it in the long run. I kept the old filter in case I need to go somewhere while the K&N filter is washed. Another benefit that justifies the extra cost is that it can provide a small increase…

In the past I have installed various individual and prefabricated air intakes on several vehicles. A sporty-sounding engine and a slight increase in consumption and performance were noticed again and again. I expected this replacement filter to be for my 2005 Saab 9-3 2.0T. This filter was a replacement for the stock air filter. It took me less than 5 minutes to install. First, I can feel increased throttle response and a LITTLE bit more power overall. Also, the turbo is now easier to rev up…

I did a lot of research on whether to use a K&N filter or an OEM stick, but in the end I chose K&N mainly because it's washable. I have a 2003 SAAB 9-3 2.0t and since it's turbocharged I figured less air restriction would also improve throttle response; I think so, but then it could just be a placebo. I have no way of measuring it. One thing I definitely noticed and I'm pretty sure it's not placebo is the sound of the turbo spinning, this thing is really howling now and I love the sound! It…
