Dinan High Flow Cold Air Intake Systems develop horsepower and torque gains by improving the engine's intake airflow. The aggressive system design provides for a less restrictive intake airflow than the stock system for greater engine efficiency and the lowest possible intake air temperatures. The Intake Systems replace the factory air box with a cylindrical performance filter and carbon fiber intake pipe. The filter is relocated to a separate compartment behind the front bumper and below the headlights in order to insulate it from engine compartment heat and maximize exposure to outside air. The filter to airflow meter pipe is designed to minimize air turbulence and maximize efficiency. The newest version of the system goes back to its carbon fiber roots for a more showroom worthy appearance complete with an embossed Dinan logo. This revised logo a marked improvement over the inset Mylar decal that was prone to marring after decades of use on the original E39 CF intake.
Features:
- More Power: + 18 HP, + 20 LB-FT (coupled w/ engine software).
- Improved throttle response.
- Optimized 4” diameter carbon fiber tube ensuring minimal turbulence.
- Updated logo for long lasting durability and aesthetic appeal.
- Uses a larger cylindrical performance filter for increased flow.
- Filter re-located to maximize exposure to cooler, oxygen rich, outside air.
- 50 State Emissions Legal: CARB EO D-176-27.

Must have for road trips
Size: 16oz (Pack of 2)
Works awesome. If you don’t use them within a year replace them. It’s way cheaper than a tow truck!

Bad Product
Size: 20oz
There was no pressure in the can. It would not even inflate a bicycle tire. Be careful there is no amazon refund or return with this item!

IT WORKS, IT REALLY WORKS!
Size: 16oz, Size: 16oz
I carry a tire plug kit in my van. Low pressure light came on and quickly made my way to air pump. Checked out tire and was at least a 5/16" bolt right between tread, very easy to locate (hissing). Inflated tire, prepared plug, pulled out bolt, inserted plug done. Almost home light came on again. Used water soap and plug was still leaking. Tried double plug and still leaking, but would take days to trigger low pressure light. Tire still had decent tread and didn't have facilities to patch, so got a can of fix a flat. I have never believed in this stuff, but it worked. No low pressure warnings for about a month. Around here they would charge $50 for a patch, 2 .25 cent soft rubber plugs and fix a flat, problem resolved!

Buy it! Lifesaver!
Size: 16oz
Yes, buy it when you don't have a spare tire because you will need it!
I live in Florida and flat tires are just part of living here!
Saved my life twice already and is absolutely self explaining!
Cheaper then a spare tire, lighter than one too! Just throw it in your trunk and best case you will never need it but just in case!
