K&N Oil Filter Review: Performance You Can Trust

K&N Oil Filter Review

K&N is not a common name among everyday Americans like FRAM or NAPA. So what is it about their oil filters that have gained a large and trusted following?  

In our K&N oil filter review, we looked specifically at the K&N HP-1010 filter by investigating its price and availability as well as many of its noteworthy features.

We concluded our review by comparing it with three other competitors.

What Is a K&N Oil Filter?

The K&N HP-1002 was originally created to fulfill auto racing needs, but it became a popular premium filter among many armchair racers and day-to-day drivers.

It features K&N’s Wrench-Off assembly, heavy-duty construction, and efficient filtering.

The K&N team featured some experienced racers who wanted a new approach to changing filters with the release of the HP-1010.

The result was K&N’s Wrench-Off filters. These filters, including the HP-1002, are designed with a hex-nut head on the upper part of the canister.

The welded head can be easily removed with a standard hex wrench.

An anti-drain back valve keeps the oil in the engine to prevent dry starts after changing filters or on cold mornings, and durable threading is resistant to stripping during installation.

The high performance filter uses a thicker canister wall for added durability against being dropped or being pelted with rocks.

The durable construction also allows for high oil pressure that would be common in the racing world with no fear of bursts.

The oil filter nut has a hole where a safety wire can be attached. This prevents a blown filter from leaving the car and becoming a hazard to other drivers. These holes are required in many racing associations.

Product Specs

The N&K HP-1002 is built with an anti-drain back valve and a bypass valve. The gasket is composed of Viton rubber.

Viton rubber is a synthetic rubber with fluoropolymer elastomers. It is commonly found in O-rings, specialty gloves, and other products.

The HP-1002 uses a high-flow premium media for filtering. A removal nut with a one-inch width is welded in place, and the product comes with a limited one-year warranty.

Pricing

During our K&N oil filter review, we found the HP-1002 oil filter priced at just over $9. This was very similar to the price of several other filters we looked at alongside the K&N filter.

These filters were all within about a dollar-and-a-half of each other. with the Mobil 1 M1-110 coming in as the outlier with a price around $15.

The M1-110 offered extended filtering efficiency and longevity beyond the other competitors in our K&N oil filter review, so the slightly higher price was to be expected. The similarity of the remaining filters made us feel they were all fairly priced.  

How It Compares

We picked a few similar products available on the market to see how they compare.

  • Napa Gold 1348 Oil Filter
  • Motorcraft FL-820-S Oil Filter
  • Mobil 1 M1-110

1. K&N Oil Filter

K&N Premium Oil Filter: Protects your Engine: Compatible with Select FORD/LINCOLN/TOYOTA/VOLKSWAGEN Vehicle Models (See Product Description for Full List of Compatible Vehicles), HP-1002
  • HIGH FLOW RATES: Designed to provide exceptional flow rates and a consistent flow of oil to your engine
  • VERSATILE COMPATIBILITY: Designed to operate with all synthetic, conventional, and blended motor oils
  • PROTECT YOUR ENGINE: Pleated synthetic-blend filtration media removes most harmful contaminants
  • EXTENSIVELY TESTED: Laboratory tested to ensure excellent capacity and burst strength
  • EASY TO REMOVE: Fast and easy Wrench-Off removal

Ease of use

Installation and removal are made easy using the Wrench-Off removal with a standard hex wrench and the provided one-inch hex nut.

Many filters now use spin-on designs that require no tools at all, but some drivers feel better with a physical nut in place. It is really a subjective choice for each driver.

Effectiveness

The HP-1002’s strong walls and overall durability are great for high oil flow rates. The anti-drain back valve is efficient at ensuring oil is available every time you start your car.

However our K&N oil filter review found other brands offered more longevity with a silicon valve instead of synthetic rubber.

Some drivers and mechanics do not like the non-traditional media that is resin-impregnated with a cotton-like consistency and features no wiring.

However, the filter is guaranteed to meet each car’s suggested oil change intervals, and it is compatible with all synthetic, conventional, and blended motor oils.

Durability

High oil flow rates are attainable because of the HP’s heavy-duty canister walls. These provide durability against bursting as well as being dropped or struck by debris on the road. K&N’s one-year warranty on a $9 part is an indicator of its durability.

2. Napa Gold 1348 Oil Filter

  • Oil Filter
  • Automotive

The NAPA 1348 Gold Oil Filter is a highly respected filter in today’s market. It uses T-03 glass-enhanced media that stands up to most competitors on the market.

The filter features a spiral-wound tube in the center of the unit that keeps all the parts together. This makes all the parts of the filter easy to maintain.

The NAPA 1348 Gold Oil Filter consistently goes beyond the recommended oil change intervals.

Ease of use

The NAPA 1348 Gold Oil Filter features a spin-on design for easy installation.

Effectiveness

The 1348 Gold can trap and securely contain up to 50 percent more debris than standard economy filters. It has tested at 99 percent efficient at 23 microns.

The 8-11-pound bypass relief valve adds to its efficiency. An anti-draw back relief valve prevents dry starts.

Unlike the K&N HP-1010 race-inspired filter, the NAPA 1348 Gold is intended for the daily grind of driving through stop-and-go traffic, construction sites, and even highway driving. The 1348 can be used with conventional, synthetic, or blended oils.

Durability

The filter’s anti-drain back valve is made of silicon so that it will not harden and become brittle over time. Many competitors use a synthetic rubber that offers less longevity and protection.

Because of its silicon design, the NAPA Gold protects your engine from dry starts even when you exceed the recommended oil change interval.

3. Motorcraft FL-820-S Oil Filter

4. Mobil 1 M1-110

Mobil 1 M1-110 / M1-110A Extended Performance Oil Filter
  • Synthetic fiber blend filter element uses advanced technology for maximum cleaning power
  • Premium lubricated filter gasket provides a tight seal and allows for easy removal
  • Heavy duty filter canister withstands 9X the normal vehicle oil system operating pressure

The Mobil 1 M1-110, along with its extended performance M1-110A model, is one of the highest rated oil filters available on the market.

The filter is especially efficient in high-mileage situations with a contaminant capacity of 28 grams: more than doubling the Motorcraft filter and many others.

The M1-110’s filter media is a synthetic blend of fibers with a multi-pass rating. The filter’s efficiency rating is a staggering 99.6 percent. Steel housing allows for strong operating pressure with no fear of bursting.

Like the NAPA 1348 Gold, the M1-110 features a silicone anti-drain back valve that resists leaking and lasts long after rubber valves have dried and cracked.

The filter is a bit pricier than the others we looked at, but it also brings added life and quality to the table.

Ease of use

Despite its durable, high-performance design, the four-ounce filter is still light enough to handle with ease, making installation easy.

Effectiveness

The M1-110 removes an impressive 99.6% of particles before they pass through your engine. Thanks in part to an advanced blend of synthetic media, this is the highest multi-pass efficiency rating we have reviewed.

The filter safely holds up to 28 grams of contaminants to allow for high-mileage changes at your discretion. In addition, the silicon anti-drain back valve prevents dry starts and leaks when you surpass your recommended oil change interval.

Durability

Housed in steel, the M1-110 can withstand up to nine times the normal operating pressure. The silicon valve also adds to the durability of the filter along with the effectiveness.

With the potential to travel many miles beyond typical oil change intervals, the silicon design prevents leaking by remaining flexible and healthy with extended longevity.

K&N Oil Filter Review: Conclusion

At the conclusion of our K&N oil filter review, we gave the HP-1010 four stars. We really liked the filter’s unique hex nut design for fast installation and removal. It is about as fast as spin-on models, but the nut gave us a feeling of extra security.

Most users will either love or hate the resin-impregnated filter media. We like it, and within the filter’s heavy-duty construction, our K&N oil filter review found it to be a great filter at a fair price.
