If you own a diesel truck, you know it's made to deliver power, longevity, and performance. But what do you do when emissions equipment begins to hold that back? That's where delete kits enter the scene — specifically, a diesel delete kit that eliminates units such as the DPF, EGR, and DEF to boost engine performance. But the question on everyone's mind is: Where can you find the best diesel delete kit to purchase?
This manual will take you through what to seek when selecting a quality kit, the importance of doing so, and where you can buy with confidence a high-performance solution for your diesel car.
What Is a Diesel Delete Kit?
A diesel delete kit is a hardware and software package employed to delete or disable stock-mounted emissions control equipment in diesel engines. These units are:
DPF (Diesel Particulate Filter)
EGR (Exhaust Gas Recirculation)
DEF (Diesel Exhaust Fluid) system
Although such systems ensure EPA emission compliance, they tend to cause:
Decreased fuel economy
Blocked filters
Constant engine regens
Expensive repairs
A diesel delete kit installation avoids these problems by removing the constrictive systems and refining the engine's performance by tuning it right.
Why Do Truck Owners Use Delete Kits?
Increased Power and Torque
With the exhaust backpressure from DPF and EGR systems removed, the engine breathes more efficiently and performs better. Power gains of 30–100+ HP are typical depending on your vehicle and tune.
Improved Fuel Efficiency
Diesel trucks with emissions systems burn fuel perpetually to clean themselves out. Removing them can increase MPG by 2–5, depending on driving style and load.
Reduced Maintenance Costs
EGR valve malfunctions and DPF blockages are prevalent — and expensive. A delete kit does away with these issue areas completely.
Increased Engine Life
Clean air running, without soot recirculation or regen cycles, means cleaner cylinders, healthier oil, and extended turbocharger life.
What to Consider in the Best Diesel Delete Kit
When purchasing a diesel delete kit, don't settle for the lowest price. A good kit should provide:
Full Components
A good kit should contain all the required hardware:
EGR block-off plates
Downpipe or exhaust replacement
DEF tank bypass/resistor plugs
Sensors required (if so)
Trustworthy ECU/TCM Tuning
Removing emissions systems involves reflashing your truck's computer (ECU). A good kit should either have a tuner or be compatible with suggested software solutions. In case of improper tuning, your truck may spit error codes or go into limp mode.
Vehicle-Specific Fitment
Don't purchase universal or "fits-all" kits. The finest diesel delete kit is specifically made for your truck year and model — guaranteeing bolt-on installation and performance safety.
Warranty or Support
A quality seller will provide technical support and warranty on parts, showing confidence in the reliability of their product.
Where to Buy the Best Diesel Delete Kit?
There are dozens of websites selling delete kits online — but few provide the combination of quality, price, and technical support serious diesel owners require.
One of the most reliable sources today is SPETuner's lineup of diesel delete kits.
Why SPE Tuner?
Vehicle-Specific Kits – They provide kits for L5P Duramax, Cummins, Powerstroke, and more.
Premium Quality Parts – Made to high levels for durability and performance.

How Much Does a Delete Kit Cost?
Pricing will depend on the truck model and what's included. On average:
EGR Delete Kits: $150–$300
Full Delete Kits (DPF + EGR + DEF): $600–$1,200
ECU/TCM Tuning: $300–$700 (if not part of kit)
It might feel like an expensive upfront purchase, but it will usually pay for itself with lower maintenance, improved MPG, and fewer visits to the shop.
Is It Legal to Use a Diesel Delete Kit?
This is an important note: Destroying emissions equipment is illegal on vehicles operated on public highways in the United States. The EPA vigorously enforces emissions controls, and employing a delete kit on a street vehicle can subject it to fines as well as failing inspection.
That being stated, delete kits are used on a regular basis and legally on:
Off-road trucks
Farm equipment
Export vehicles
Race or competition-use trucks
If your truck is one of the above, a delete kit is a sensible and effective solution. If not, check local laws first.
Installation: DIY or Pro?
Most kits are DIY-friendly, particularly if you have mechanical skills and basic tools. But if you're inexperienced in diesel performance or require tuning assistance, professional installation is advised to prevent damage or incomplete deletion.
A pro can:
Ensure accurate tuning and calibration
Mount exhaust and EGR components firmly
Avoid check engine lights or limp mode problems
Final Thoughts
If you want to return your diesel truck to its full capabilities, cut maintenance expenses, and increase overall drivability, a delete kit is one of the most effective upgrades you can install — provided it's used lawfully.
The best source for a diesel delete kit is a place that offers quality, vehicle-specific engineering, and solid support — and SPETuner is that place.
Don't accept inferior parts or unknown tuners from questionable websites. Your truck is worth a proven solution supported by real-world experience and performance-verified results.
