How We Picked These Intakes
You want an intake that fits your car, your budget, and your goals. We prioritized: compatibility and fit (vehicle-specific kits or hoses that replace worn OEM parts), build materials (silicone, mandrel-bent aluminum, quality filters, heat shields), proven performance or dyno testing where available, ease of installation for DIYers, and overall value including warranty and long-term durability.
We also considered user ratings and manufacturer reputation so you’re not left guessing about real-world results.
WEIGONG Cold Air Intake Kit
If you’re looking to freshen up the airflow on your IS300 without getting into a full engine overhaul, this WEIGONG cold air intake kit is a straightforward option. It swaps in a multi-layer filter and includes a heat shield to help keep intake temps down. You’ll notice cleaner air delivery thanks to the claimed ≥99% filtration, which can reduce engine wear and help maintain fuel efficiency over time.
Installation is billed as quick and tool-free, so it’s an easy weekend tweak whether you’re trying to keep daily commute temperatures under control or prepping the car for a spirited weekend drive. The silicone sealing edge and reinforced structure mean it’s built with weather exposure in mind — good if you park outside or take the car on dusty roads. If you want a simple, no-fuss intake upgrade that focuses on filtration and basic protection rather than radical power gains, this is worth considering.

FAQ
How Do I Choose The Best Cold Air Intake For My Lexus Is300?
You should start by confirming the exact model year and engine since fitment varies a lot between the 2001–2005 IS300 and later models. Prioritize fitment first — some kits are made for 2001–2005 IS300s (including dedicated intake hoses and short-ram style kits), while others like the WEIGONG tip kit target later Lexus/RC/IS variants.
Think about the filter type and maintenance: a washable dry filter is easy to care for and common on higher-end AEM-style systems, while budget kits often use simpler filters. Consider build materials and heat protection because mandrel-bent aluminum tubes and a proper heat shield reduce intake air temperature and heat soak. Check whether the kit keeps or relocates the MAF sensor and PCV/CCV fittings so you don’t end up with vacuum leaks.
Finally, verify local emissions rules and whether the kit is street-legal where you live before you buy.
Will Installing A Cold Air Intake Trigger A Check Engine Light Or Require An Engine Tune?
You might get a check engine light if the new intake changes the airflow enough to confuse the MAF sensor or if any vacuum lines are not reconnected properly. Many vehicle-specific systems are designed to work with stock engine management and won’t need a tune, especially those that retain the MAF location or use carefully matched tubing.
However, aggressive intakes that move the MAF or dramatically increase airflow can benefit from a tune to optimize fueling and get the most reliable performance. Always clean and inspect the MAF sensor after installation, and make sure couplers and clamps are tight.
If a CEL appears, check for loose hoses or connectors first, and if the problem persists, get either a custom tune or a MAF recalibration from a reputable shop.
How Should I Install And Maintain A Cold Air Intake For Reliable Performance?
You can install many cold air intakes yourself with common hand tools in about an hour or two, but make sure you follow the manufacturer instructions and torque clamps securely to avoid leaks. Position intake tubing away from hot engine components and verify any heat shield is seated correctly to reduce heat soak. For maintenance, clean reusable/washable filters according to the maker’s schedule — typically after extended dusty use, otherwise every 20,000–50,000 miles depending on conditions — and inspect hoses, clamps, and mounting points for wear or cracking regularly. Avoid driving through deep water that could cause intake hydrolock and periodically check the MAF sensor for contamination; a quick sensor cleaning can prevent drivability issues.
If you’re ever unsure about fitment or tuning, a professional install and inspection will save time and reduce the risk of problems.
Buyers Top Picks
When choosing between the WEIGONG, AEM S.R.S., and Suride cold air intakes for your Lexus IS300, you’ll typically prioritize how well the kit fits and the real-world performance and sound improvements it delivers, plus whether it installs easily without modifications. You’ll also weigh build quality, filter type, price, and warranty so you can pick the one that best balances power gains, durability, and value for your needs.
Wrapping Up
Choose AEM if you want the most reliable performance upgrade with proven gains and a high-quality filter. Pick Mishimoto if your priority is replacing an aging hose and improving durability. If you’re on a tight budget or want a simple sound and look upgrade, the Suride or PHILTOP kits give good value and easier installs. If you own a 2016–2020 IS300/IS200T/RC200 and want a model-specific tip kit, the WEIGONG option targets those years but costs more.
In short, match the kit to your model year and goals — whether that’s top performance, longevity, easy installation, or the best price — and you’ll get the most satisfaction from the upgrade.
