I did a lot of research before I chose TruPower Cold Air Intake by Stillen. Others have the plastic see through cover that will not insulate the intake properly. I guess it looks cool and you can easily see the filter. However, I went for the functional purpose of True Cold Air. I also loved the idea of the secondary air source coming from the front grill. The design was great and the quality is very good. Step by step instructions were super helpful specially since it’s one of the only cold air intakes requiring to removed your front bumper/grill. All that detail, testing, and results shared made me comfortable with the choice I made purchasing this item. The cold air intakes with the tuner combined have improved the performance of my truck. Thanks for creating such great products Stillen. Now I just need to make time to install the inner cooler relocation kit to complete the combo.
I have recently go into the z34 community and Stillen has always been the first name I heard been assicoated with Zbrand, therefore when it came down to picking out the exhaust system for my 370z, I couldn't help but go with Stillen. Thus far everything, look amazing and sound I'll install the system live on with that Stillen legacy on my 370z.
I have a 2024 Toyota Tacoma TRD Offroad with the 2.4 L turbo. I purchased the Stillen 3 inch axle dump off road cat back system and the ram air kit. In combo with bigger boost tubes bigger 58 mm turbo, BOV, Pedal Commander and JDM stage 3 tune. The Tacoma breathes so much better and the race exhaust sounds great, not obnoxious like when people just cut off the muffler. I'm really happy with the performance and how quick it shipped. My GF just got the new Toyota 4Runner TRD Offroad and I plan on getting her the same set up.
What a difference! Best hands down air intake and its screams!
Had one 5 years ago but I needed to upgrade to a newer one! Boy does this air intake deliver! Its screams and sounds so good! What a difference! Hands down the best air intake on the market for my 2011 Nissan Maxima SV!
Very happy. Sound is much improved over stock. Installation was very straightforward. Most of the time was getting the old exhaust off. Fitting the new Stillen cat back was very easy.
