Magnum Force Stage 2 Aluminum Black Cold Air Intake System with Pro 5R Filter (54-11872-1) by aFe. The aFe Stage 2 Cold Air Intake System replaces your entire factory air intake system with a large high-flow aFe air filter, open element airbox/heat shield and a smoothly contoured, less restrictive intake tube. This system enables your engine to take in huge quantities of dense, cool, oxygen laden air. The result is better combustion, increased horsepower and torque, and a noticeable gain in performance.

The Stage 2 Cold Air Intake System will give you the greatest possible performance gain and the most bang for the buck. It replaces your factory, restrictive air intake system with the massive aFe performance air filter of your choice, a one-piece open element airbox/heat shield that seals against the hood, isolating the filter from engine heat, and a rotomolded plastic intake tube with smooth bends for increased airflow volume. The increased flow of cooler air to your engine will result in noticeable gains in power and performance. Cooler, denser air contains more oxygen, and more oxygen in your engine's air intake charge means better combustion, resulting in greater engine output.

The aFe Pro 5R air filter was designed to provide the maximum airflow possible, to enable your engine to make the most horsepower and torque. But aFe didn't achieve this by ignoring engine protection. The Pro 5R outperforms most other cotton gauze air filters with a 98.6% efficiency rating. The increased airflow and high filtration capability are the result of the Pro 5R's construction. It's made of 5 layers of progressively finer medical-grade cotton gauze.

The Pro GUARD 7 air filter delivers increased airflow while providing the highest level of filtration efficiency available 99.7%. The patented 7-layer progressive cotton/synthetic media in the Pro GUARD 7 consists of 5 layers of progressively finer medical grade cotton gauze, combined with 2 layers of non-woven synthetic polyester fabric with random porosity.

Competitors use constant size mesh gauze in their filters, which creates voids/openings that can allow dirt to pass through. As the progressively finer layers of gauze are stacked in the Pro 5R and Pro GUARD 7, the randomness of the openings increase, minimizing spaces with no filter media. Dust accumulates on multiple layers, increasing overall dust holding capacity and filtration efficiency.

The Pro DRY S filter combines high airflow and filtration efficiency with the convenience of oil-free maintenance. It contains 3 layers of randomly porous synthetic fabric, which allows approximately twice the airflow when compared to a typical stock air filter. The increased airflow results in more horsepower and torque, better throttle response and more miles per gallon. But this improved airflow and performance hasn't been gained at the expense of engine protection. The Pro DRY S has an excellent 99.2% filtration efficiency rating.

The pleats in all 3 filters are evenly spaced for greater dust holding capacity and the tips are rounded for better airflow. They're also 30% deeper than comparable aftermarket air filters for longer service intervals and greater dust holding capacity. The sealing surface and supporting structures are made from 100% polyurethane, to withstand extreme engine temperatures.

Powder-Coated One-Piece Heat Shield blocks performance-robbing engine heat. This heat shield requires no assembly and uses factory mounting locations for fast and easy installation.

A specially developed 3-angle velocity stack smoothes the airflow transition from the air filter to the rotomolded intake tube. The precision design and smooth contours of the intake tube maximize airflow volume and speed for optimum power gains.

The aFe Stage 2 Air Intake System comes complete with everything necessary for installation, including comprehensive instructions. It's backed by aFe's limited 2-year warranty and made in the USA.

Great fit and makes potty training easier
Size: 3T-4T, Unit Count: 84
These training pants have been a big help during potty training. They fit comfortably and feel soft against the skin, more like real underwear than a diaper. The stretchy sides make them easy for little ones to pull up and down on their own, which really helps with independence. They do a good job holding small accidents without leaking, and the fun character designs make my little one more excited to wear them. The pack comes with plenty to last through the training phase, which is nice when you’re going through a few each day. Tip: keep a few extras in the car or diaper bag for outings. It makes potty training on the go so much easier.

Great Pull-ups that Don't Leak!
Size: 3T-4T, Unit Count: 20
I was on the hunt for the perfect potty training pants for my little guy, and Pull-Ups Boys' Potty Training Pants in size 3T-4T turned out to be a great find. We’ve tried a few different brands, but these have been the most reliable. The design is fun and colorful, which my son loves, and it makes him excited to wear them. The fit is spot on for his size (32-40 lbs), and he moves around comfortably without any leaks. The absorbency is impressive – it gives me peace of mind knowing accidents won’t mean a complete outfit change. Overall, these Pull-Ups have made the potty training process a lot smoother for both of us. There are a few things to note, though. The price is a bit higher compared to some other brands, but I believe the quality justifies it. Also, while they are great during the day, we still need a bit more protection at night. I find myself using an extra layer for nighttime just to be safe. The packaging could also be improved – a resealable option would be nice to keep the remaining training pants fresh and organized. Despite these minor issues, I’m really happy with the product, and my son is well on his way to being fully potty trained. Pros: - Fun and colorful design that my son loves - Perfect fit for 32-40 lbs, allowing comfortable movement - Excellent absorbency, minimizing leaks - Helps make the potty training process smoother Cons: - Slightly higher price compared to other brands - Not as effective for overnight use, requiring additional protection - Packaging lacks a resealable option for convenience

These training pants are amazing. My son uses them whenever he’s taking a nap or sleeping throughout the night. I’ve ordered these multiple times and we’ve never had an issue with leaking.

Great for potty training
Size: 3T-4T, Unit Count: 20
We really like these pull ups and they have worked well for us during potty training. They are easy to pull on and off, which is great for toddlers who are learning to be more independent. They fit well and do a good job containing messes without leaking. I also like that they feel comfortable and not too bulky, so my child can move around easily. Overall, these have been a reliable option for us and something we continue to use during this stage.
