Standard Motor Products DIH4 Diesel Air Intake Heater
This item is an intake heater element replacement designed as an OE-style part. The listing identifies the product type as an auto part with compact package dimensions. It is manufactured in Ireland and intended for use where the original intake heater has failed or requires replacement.
Key details to consider: the DIH4 is a direct-replacement style heater, typically used to maintain intake air temperature in cold conditions to support reliable cold starts and reduced white smoke. The small form factor suits stock intake housings. Check electrical connector and mounting compatibility before purchase to ensure fitment with your 7.3L intake assembly.
Boosted Performance 7.3 Powerstroke Cold Air Intake System
The Boosted Performance system is a full 4-inch cold air intake engineered for 1999–2003 7.3 Powerstroke trucks. The manufacturer claims up to 15 WHP and 25 WTQ gains through a larger diameter design and open-intake flow path.

Design and performance aspects: This intake emphasizes a significant increase in airflow versus factory closed-box systems, with benefits listed as faster turbo spool, improved throttle response, and potential fuel economy gains. Installation is a direct-replacement for the specified model years. Consider material finish, mounting points, and whether the open intake requires additional shielding for off-road or dusty environments.
PHILTOP 4″ Cold Air Intake Kit System + Heat Shield
PHILTOP supplies a complete intake kit for 1999–2003 Ford F250/F350 and 2000–2003 Excursion 7.3L engines. The kit includes an air filter, intake tube, silicon hoses/connectors, and a heat shield intended to reduce heat soak from the engine bay.
Performance and fitment notes: The brand claims increases in acceleration and towing power, citing an estimated 14 horsepower and 13 ft-lbs of torque improvement. The inclusion of a heat shield is relevant for maintaining lower intake air temperatures under load. Verify that the kit matches your truck’s exact year/configuration as recommended by the seller before installing.
PMFCA Oiled Cold Air Intake 7.3 Diesel Kit
The PMFCA kit lists compatibility across 1995–2003 7.3L Powerstroke trucks and focuses on durable aluminum construction with CNC mandrel bends to maximize airflow. The kit includes an oiled filter and emphasizes heat and corrosion resistance.

Technical considerations: CNC mandrel-bent tubing reduces internal turbulence compared to crimped bends, which can help maintain higher volumetric flow. The oiled filter requires routine maintenance (cleaning/oiling) to preserve filtration efficiency. This kit’s broader fitment range may make it suitable for earlier 7.3 models, but confirm hardware and sensor locations for your specific year.
AceRide Oiled Cold Air Intake Kit Compatible With Ford F250 F350
AceRide offers a plug-and-play style kit for 1999.5–2003 7.3L trucks including intake pipe, oiled filter, silicone pipe, mounting bracket, and hardware. The listing highlights improved airflow and engine efficiency as performance outcomes.
Fitment and maintenance: This kit’s inclusion of mounting hardware supports a direct replacement approach. The oiled filter maximizes airflow but requires periodic servicing. If you prioritize a balance of easy installation and flow improvement, this kit is positioned as a straightforward option for late-1990s to early-2000s 7.3L Powerstroke applications.
Buying Guide: How To Choose The Right Intake Heater Or Cold Air Intake For A 7.3L
Selecting the right component depends on vehicle year, intended use, and environmental conditions. Below are factors to evaluate before purchasing.
Fitment And Compatibility
- Exact Model Years: Confirm whether the item lists precise year ranges (e.g., 1999.5–2003). Small differences in sensor locations or snorkel size can affect fit.
- Turbo/Compressor Differences: Some hoses or intakes are sized for upgraded compressor housings; verify inlet diameters match your turbocharger.
Type: Heater Element Versus Cold Air Intake
- Intake Heater Element (like the DIH4) maintains warmer intake air in cold climates to reduce white smoke and improve cold starts. Useful if your truck still uses a stock intake housing where a heater plugs in.
- Cold Air Intake Systems are designed to increase airflow and lower intake temperatures; some use open elements which can improve throttle response and turbo spool.
Materials, Construction, And Heat Management
- Tube Material: Aluminum with mandrel bends preserves cross-sectional area for smooth flow. Powder-coated finishes resist corrosion.
- Heat Shields: Kits that include a heat shield help isolate the filter from engine heat, especially important under towing or heavy-load conditions.
- Silicone Connectors: Quality silicone couplers resist heat and pressure; check ply rating and temperature range if available.
Filter Type And Maintenance
- Oiled Filters offer higher airflow but require scheduled cleaning and re-oiling to maintain filtration and prevent contamination downstream.
- Dry Filters require less maintenance but sometimes sacrifice peak airflow compared to oiled media.
Performance Claims And Real-World Expectations
- Manufacturers often quote WHP/Wtq gains; expect variability depending on engine condition, exhaust, tuning, and altitude.
- Cold air intakes improve throttle response and spool only if the rest of the system (exhaust, turbo) allows additional airflow.
Installation And Wiring
- Plug-and-Play Kits will include mounting brackets and hardware; check whether additional trimming or minor modifications are required.
- Intake Heater Replacement may require verifying electrical connectors and ensuring proper grounding and fuse protection to match vehicle circuits.
Environmental And Usage Considerations
- For dusty or off-road use, prefer enclosed filters or add filtration pre-filters to open-element intakes.
- If you operate frequently in extreme cold, an intake heater element can complement a cold-air kit or be preferable when maintaining OEM heating function.
Comparison Perspectives
- Cold Weather Reliability: DIH4-style heater elements focus specifically on cold start reliability; cold air kits prioritize airflow and performance.
- Performance Versus Maintenance: Oiled filters boost flow but demand upkeep. If minimal maintenance is a priority, consider a dry media option or a sealed intake housing.
- Durability: CNC mandrel-bent aluminum and powder-coated finishes offer longevity compared to cheaper stamped or crimped tubing.
- Value: Consider the completeness of the kit—does it include a heat shield, silicone couplers, hardware, and filter? Kits that supply everything reduce accessory purchases.
When evaluating any intake heater or cold air intake for the 7.3L Powerstroke, verify fitment for your specific model year and service history. Weigh the trade-offs between cold-weather starting reliability and long-term airflow gains when choosing between an intake heater element and a full cold air intake system.
